Geometry of Obstructed Families of Plane Algebraic Curves and Projective Hypersurfaces
Anna Gourevich
4:00pm|S-101

I will talk about families of plane curves, and more generally projective hypersurfaces, of given degree having one isolated singularity of prescribed analytic type. We will see an example of such family and discuss its geometry.

Matrix Rigidity
2:00pm|S-101

A rigid matrix is a matrix that cannot be represented as the sum of a low rank matrix and a sparse matrix. Constructing explicit rigid matrices (for certain parameters of rank and sparsity) is a long standing open problem with applications to...

Coulomb Gas in Two dimensions
2:00pm|S-101

I will review the definition and the interest in the statistical mechanical model called "Coulomb Gas". Past results and possible new ones will be briefly discussed.

Some Extremal Functions in Fourier Analysis and Applications to Number Theory
4:00pm|S-101

I will give an overview on the recent developments on the Beurling-Selberg problem of majorization by entire functions of exponential type, in joint works with J.D. Vaaler (Texas) and F. Littmann (North Dakota State). These provide new applications...

Contact Structures, Open Books, and Support Genus
John Baldwin
2:00pm|S-101

A contact structure is a geometric structure on a 3-manifold (in general, on a 2n+1 manifold) which arises naturally when studying symplectic 4-manifolds. In this talk, I'll describe an important correspondence between contact structures and open...

Big Gaps in Zeros of L-Functions
2:00pm|S-101

Abstract: The first zeros Riemann Zeta function occur at approximately 1/2 +- 14.13i. In 1999 Steven D. Miller showed that among all L-functions of a certain type, the Riemann Zeta function has the largest such gap around zero. I'll discuss how to...
