Spectacle cycles and modular forms  
Dr Jens Funke (Durham university)  
27 May 2010  Harrison 203 Thursday 3pm  Pure Mathematics 
The classical Shintani lift is the adjoint of the Shimura correspondence. It realizes periods of even weight cusp forms as Fourier coefficients of a halfintegral modular form. In this talk we revisit the Shintani lift from a (co)homological perspective. In particular, we extend the lift to Eisenstein series and give a geometric interpretation of this extension. This is joint work with John Millson.

Padic interpolation of automorphic forms  
Dr David Loeffler (University Warwick)  
4 Mar 2010  Harrison 106 Thursday 3pm  Pure Mathematics 
Coleman’s work on overconvergent padic modular forms shows that finite slope modular eigenforms can be interpolated padically, forming rigidanalytic families of eigenforms parametrised by their weights. This has been generalised by Emerton to cohomological automor phic representations of a wide range of reductive groups, where the local factor at p is principal series. I shall give an exposition of Emerton’s construction, and of recent joint work with Richard Hill and myself in which we have extended this to certain nonprincipalseries cases

On volumes of arithmetic hyperbolic norbifolds.  
Dr Mikhail Belolipetsky (Durham University)  
15 Feb 2010  Harrison 106 Monday 2pm  Pure Mathematics 
The main topic of my talk is the search for the minimal volume quotients of the hyperbolic nspace. In dimension 2 the problem was solved by Siegel who also asked about the general case. Since then a considerable progress has been made for the socalled arithmetic quotients and the only case which was still open is when the dimension n is odd and >3. After a brief introduction I will focus on the solution to this problem which we obtained in a recent joint work with Vincent Emery.  
 
Weiestrass Points and Automorphisms of Curves  
Dr Kay Magaard (University of Birmingham)  
11 Feb 2010  Harrison 106 Thursday 3pm  Pure Mathematics 
Let $X$ be a compact connected Riemann surface of genus $g \geq 2$. A point of $p \in X$ is Weierstrass if there exists a nonconstant meromorphic function on $X$ that has a pole of order $\leq g$ at $p$ and is holomorphic on $X \setminus p$. A lemma of Sch\"oneberg asserts that if an automorphism $\alpha$ of $X$ fixes five or more points of $X$, then every one of them is a Weierstrass point. In the talk we will discuss the impact of Sch\"oneberg's lemma has on the structure of the automorphism group of $X$.  
 
Nonresidually finite extension of arithmetic groups.  
Dr Richard Hill (University College London)  
8 Feb 2010  Harrison 106 Monday 2pm  Pure Mathematics 
Let Gamma be an arithmetic group with the congruence subgroup property, and with an associated Shimura variety. A theorem of Deligne states that there is a central extension of Gamma by a cyclic group which is not residually finite. This result was used by Toledo to give examples of complex projective varieties for which the topological fundamental group does not embed in the algebraic fundamental group. In the talk I'll generalize Deligne's result to the case that Gamma has no associated Shimura variety, so for example my result holds for congruence subgroups of SL(n,Z) with n at least 3.

The Manin constant of elliptic curves over function fields  
Dr Ambrus Pal (Imperial College)  
30 Oct 2008  Harrison 101 Thursday 3pm  Pure Mathematics 
We study the padic valuation of the values of normalized Hecke eigenforms attached to nonisotrivial elliptic curves defined over function fields of transcendence degree one over finite fields of characteristic p. Under certain assumptions we compute on the smallest attained valuation in terms of the minimal discriminant. As a consequence we show that the former can be arbitrarily small. We also use our results to prove for the first time the analogue of the degree conjecture unconditionally for infinite families of strong Weil curves defined over rational function fields

Algebraic surfaces and hyperbolic geometry  
Prof. Burt Totaro (Cambridge university)  
16 Oct 2008  Harrison 101 Thursday 3pm  Pure Mathematics 
The intersection form among curves on a complex algebraic surface always has signature (1,n) for some n. So the automorphism group of an algebraic surface always acts on hyperbolic (n1)space. For a class of surfaces including K3 surfaces and many rational surfaces, there is a close connection between the properties of the variety and the corresponding group acting on hyperbolic space  
 
Rational points of definable sets and diophantine problems  
Dr. Jonhatan Pila (Bristol University)  
9 Oct 2008  Harrison 101 Thursday 3pm  Pure Mathematics

More specifically, definable sets in ominimal structures. I will describe a result, joint with Wilkie, that such a set $X$ can have only ``few'' rational points, in a density sense, that do not lie on some positive dimensional connected semialgebraic subset of $X$.I will give some applications to problems of AndreOortManinMumford type, including a new proof, joint with Zannier, of the ManinMumford conjecture, and some variant special cases of results of AndreOort and mixed AndreOortManinMumford type.

Integral Points on Curves of Higher Genus  
Samir Siksek (Warwick)

For many curves of higher genus, Baker's Theory provides (astronomical) bounds for the size of integral points. I explain how to combine Baker's bounds with the MordellWeil sieve to compute all the integral points on some curves of higher genus. This is based on joint work with Bugeaud, Mignotte, Stoll and Tengely.

HopfGalois Module Structure of Tame Extensions of Prime Power Degree  
Paul Truman (University of Exeter)  
4 Mar 2008  Harrison 103 Tuesday 9am  Pure Mathematics (Internal) 
A major result in local Galois module theory is Noether's Theorem, that given a finite Galois extension of local fields L/K, the ring of integers OL is free over the integral group ring OK[G] if and only L/K is at most tamely ramified. In HopfGalois module theory, the Galois group is replaced by a (possibly nonunique) Hopf algebra, giving a socalled HopfGalois structure on the extension, and the behaviour of OL in this HopfGalois structure is studied. We present a generalisation of Noether's Thereom to this setting for Galois extensions of prime power degree.

Some examples of local Galois module structure in characteristic 0 and characteristic $p$.  
Nigel Byott (University of Exeter)  
26 Feb 2008  Harrison 103 Tuesday 9am  Pure Mathematics (Internal) 
Let $L/K$ be a totally ramified abelian extension of local fields, with Galois group $G$. A basic question in Galois module structure is to determine when the valuation ring $S$ of $L$ is a free module over its associated order in the group algebra $K[G]$. When $K$ is a finite extension of $\mathbb{Q}_p$ (the characteristic $0$ case), Y.~Miyata has given a freeness criterion for a large family of {\em cyclic} extensions of degree $p^n$. In this talk, I will give an alternative formulation of Miyata's criterion, and will present work in progress (joint with Griff Elder), where the same freeness criterion arises for {\em elementary abelian} extensions of the field $K=\mathbb{F}_q((T))$ of formal Laurent series over a finite field (the characteristic $p$ case).  
 
Growth in linear algebraic groups: an approach through incidence  
Harald Helfgott (Bristol)  
21 Feb 2008  Harrison 106 Thursday 3pm  Pure Mathematics 
Let K be R, C or a Z/pZ. Let G = SL_2(K). Not long ago, I proved the following theorem: for every subset A of G that is not contained in a proper subgroup, the set A\cdot A\cdot A is much larger than A. A generalisation to groups of higher rank was desired by many, but seemed hard to obtain. I shall now present a proof somewhat different from the first one. The role of both linearity and the group structure of G should now be clearer. A few ideas towards a generalisation will be discussed, with a focus on the case of SL_3(Z/pZ).

Siegel modular forms and representation numbers of quadratic forms  
Lynne Walling (Bristol)  
22 Nov 2007  Harrison 106 Thursday 3pm  Pure Mathematics 
Number theorists love to count things, especially integral objects. An example is to count the number of ways an integral quadratic form represents each integer, where the variables of the quadratic form are only allowed to assume integral values. More generally, we can ask to count the number of ways a quadratic form represents a lower dimensional quadratic form. These representation numbers are encoded in the Fourier coefficients of generalized theta series, which are examples of modular forms. When counting representation numbers of integers, the associated theta series is a function of one complex variable, whereas to count representation numbers of rank n quadratic forms, the associated theta series is a function of an n by n symmetric complex matrix. We will discuss these theta series, with particular attention given to the Hecke operators and the information they provide regarding representation numbers.

Wild ramification in extraspecial extensions  
Griff Elder (Virginia Tech / University of Nebraska at Omaha)  
21 Jun 2007  Harrison 106 Thursday 2pm  Pure Mathematics 
It was observed, with J. Hooper, that sharp lower bounds for the largest ramification break number in quaternion extensions of dyadic local number fields depend upon the refined ramification filtration, as defined with N. Byott. Moreover, quaternion counterexamples to the conclusion of HasseArf require that this refined filtration be extreme in two different ways. In this talk, we will extend these results to a more general class of nonabelian extensions that includes extraspecial extensions. To keep complications to a minimum, we will work over characteristic $p$ local fields.

On the continuous part of codimension two algebraic cycles on certain threefolds over a field

15 Feb 2007  Harrison 106 Thursday 3pm  Pure Mathematics 
Let X be a nonsingular projective threefold over a field with resolution of singularities, and let A^2(X) be the group of algebraically trivial codimension 2 algebraic cycles on X modulo rational equivalence with coefficients in Q. Assume X is birationally equivalent to another threefold X' admitting a fibration over a curve whose generic fiber F satisfies the following three conditions: (i) the motive M(F) is finitedimensional, (ii) for ladic etale cohomology H^1(F)=0 and (iii) H^2(F) is spanned by divisors on F. We prove that, provided these three assumptions, the group A^2(X) is weakly representable: there exists a curve Y and a correspondence z from Y to X, such that z induces an epimorphism A^1(Y) > A^2(X), where A^1(Y) is isomorphic to Pic^0(Y) tensored with Q. In particular, the result holds for threefolds birational to threedimensional Del Pezzo fibrations over a curve.

Real K3 surfaces  
V. Nikulin (Liverpool)

Up to deformation, there are three real types of
elliptic curves which depend on the number of real ovals: 0, 1 or 2.
All elliptic curves are hyperelliptic, and their real forms
can be obtained by the double covering of P^1/R ramified in four
points, some of them conjugate. This gives equations of real
elliptic curves.
K3 surfaces give a 2dimensional generalization of elliptic curves. What about similar results for them? This will be the subject of the talk.

Polynomial invariants of links, graphs, and matroids  
S Huggett (Plymouth)

We review the relationships between links, graphs, and matroids. In particular, given a planar graph there are two wellestablished methods of generating an alternating link diagram. Switching from one of these methods to the other corresponds in knot theory to tangle insertion in the link diagrams, and in combinatorics to the tensor product of the cycle matroids of the graphs. We show how the Jones and Tutte polynomials behave under these operations.
