Weight-monodromy conjecture for certain threefolds in mixed characteristic
The aim of this paper is to give a proof of the weight-monodromy conjecture for a threefold which has a projective strictly semistable model such that, for each irreducible component of the special fiber, the Picard number is equal to the second

What I termed the ``Shimura-Taniyama-Weil'' conjecture became known as the ``modular curve conjecture'' and then, from the summer of 1999, as the ``modular curve theorem'' after the work of Breuil, Conrad, Diamond, and Taylor in the same vein as the work of Wiles and Taylor for the ``semi-stable'' case.
This conjecture, even as a conjecture, has served as an important motivating example for the idea of the ``Langlands Program'', or perhaps of an extension of that program, that certain kinds of objects in geometry should give rise to certain group representations.
The conjecture states that the L-function of an elliptic curve defined over $\Q$ with conductor $N$ arises from a cuspform for the group $\Gamma_0(N)$ that is compatible with the substitution in the upper-half plane $H$ given by $W_N$\@.

Conjecturally the Zariski closure of the orbits of the Hecke symmetries are exactly the closures of ``leaves'' in Oort's foliation.
This applies to a conjecture of Prasad on autodual representations of division algebras.
The ingredients of the proof are to prove a special case of the Hodge standard conjecture, and apply an argument of Steenbrink, M. Saito to the weight spectral sequence of Rapoport-Zink.

We specify a set of weights, determined by the restriction of \rho to the inertia subgroup at P, which contains all the weights for which \rho is modular (and, conjecturally, nothing else; we have partial results in this "converse" direction).
These conjectures are much more precise in the case of abelian extensions, and over the years a number of generalizations and/or refinements have been made.
Abstract: Recent conjecture of Kontsevich-Soibelman and Gross-Wilson asserts that the Gromov-Hausdorff limit of a maximally degenerate Calabi-Yau family is a sphere with Monge-Ampere Kahler affine structure with singularities in codimension 2.

An old conjecture holds that the number N_n(X) of degree n number fields with discriminant less than X is asymptotic to c_n X when X grows and n is fixed.
There's a slight wrinkle: the weight 1 Hilbert modular form f attached to E[3] by Langlands-Tunnell might not be ordinary, and thus one cannot necessarily find a higher-weight modular lift of E[3] whose restriction to decomposition groups at 3 we can control.
We give an example showing two dessins with the same monodromy group and local ramification data which are separated by the braid group invariant.

Modular forms of half-integral weight are more difficult to deal with, but Shimura proved a nice correspondence from these forms to modular forms of integral weight.

In this talk, I will describe one of these conjectures in some detail, illustrating it in some cases where it is known, and explain some of my work towards proving it in the case when the variety is a self-product of the Fermat curve, $${\mathbf F_N}: X^{N}+Y^{N}+Z^{N}=0$$.

The Seifert conjecture is the assertion that a smooth nonvanishing vector field on the three sphere must have a closed trajectory.
The Seifert conjecture is the question, posed by Seifert (1950), whether or not every smooth non-vanishing vector field on the 3-dimensional sphere has a periodic orbit.

 Abstract   (Site not responding. Last check: 2007-09-18)
In this talk, I will give a proof of the weight-monodromy conjecture (Deligne's conjecture on the purity of monodromy filtration) for varieties with p-adic uniformization by the Drinfeld upper half spaces of any dimension.
The ingredients of the proof are to prove a special case of the Hodge standard conjecture, and apply an argument of Steenbrink, M. Saito to the weight spectral sequence of Rapoport-Zink.
As an application, by combining this result with the results of Schneider-Stuhler, we compute the local zeta functions of p-adically uniformized varieties in terms of representation theoretic invariants.

Weil (\cite{weilmathann}) showed that the cuspforms of weight \(2\) for the group \(\Gamma{}_{0}(N)\) satisfying the appropriate functional equation under the mapping of \(H\) given by \(W_{N}\) correspond precisely to Dirichlet series with certain growth conditions that admit analytic continuations as meromorphic functions in \(\mbox{\textbf{C}}\) satisfying a finite number of ``twisted'' functional equations.

When $a\sb p=0$, we are able to decompose both the sum and the difference of the two unbounded distributions attached to $f$ into a bounded measure and a distribution that accounts for all of the growth.
Moreover, we interpret Kurihara's conjectures on the Galois structure of the Tate-Shafarevich group in terms of these two Iwasawa functions.

In a recent paper, Calegari and Dunfield exhibit a sequence of hyperbolic 3-manifolds which have increasing injectivity radius, and which, subject to some conjectures in number theory, are rational homology spheres.
We prove unconditionally that these manifolds are rational homology spheres, and give a sufficient condition for a tower of hyperbolic 3-manifolds to have first Betti number 0 at each level.
This conjecture was proved by Davenport and Heilbronn for n = 3, and recently for n = 4,5 by Bhargava.

Let M be a space of weight 2 cuspidal modular symbols with trivial character, which is the kernel of an ideal in the Hecke algebra.
We assume that M has weight two and trivial character; the modular degree of M is then the square root of the order of ModularKernel(M).
The real and minus Tamagawa numbers are defined even for higher weight spaces of modular symbols over the rationals.

It is known that the construction of the weight spectral sequence follows from an identification of the graded pieces of...
