Computer Science/Discrete Mathematics Seminar I

An Optimal Lower Bound for File Maintenance
11:15am|S-101

In the file maintenance problem, n integer items from the set {1,....,r} are to be stored in an array of size m>=n . The items are presented sequentially in an arbitrary order and must be stored in the array in sorted order (but not necessarily in...

Poisson Statistics and the Value Distribution of the Epstein Zeta Function
Anders Sodergren
4:30pm|S-101

We will discuss the value distribution of the Epstein zeta function E_n(L,cn) for real c and a random lattice L of covolume 1 and large dimension n. Important ingredients in our study will be the distribution of vector lengths in a random lattice as...

On How the First Term of an Arithmetic Progression Can Influence the Distribution of an Arithmetic Sequence
4:30pm|S-101

In this talk we will show that many arithmetic sequences have asymmetries in their distribution amongst the progressions mod q. The general phenomenon is that if we fix an integer a having some arithmetic properties (these properties depend on the...

Heights, Discriminants and Conductors
4:30pm|S-101

In this talk we consider the problem of giving explicit inequalities which relate heights, discriminants and conductors of a curve defined over a number field. We present such inequalities for some curves, including all curves of genus one or two...

Joint IAS/Princeton University Symplectic Geometry Seminar

Bubbles and Onis
Urs Frauenfelder
4:30pm|S-101

This is joint work with Peter Albers. We study a Floer gradient equation on a very negative line bundle over a symplectic manifold. If the line bundle is negative enough there are generically no holomorphic spheres. We explain the metamorphosis of...

Spectral Factors in Endoscopic Transfer
4:30pm|S-101

This talk is based on some results for real groups used in Arthur's classification of global packets for classical groups. The setting is twisted endoscopy for a connected reductive algebraic group over the reals. There is a geometric transfer which...
