Complex Algebraic Geometry

Singularities and Spaces of Jets
1:00pm|S-101

I will give an introduction to spaces of jets of algebraic varieties, explining their relevance for birational geometry. In particular, I will explain why these spaces are useful in the study of singularities.

New Correlation Bounds for GF(2) Polynomials Using the Gowers Norm
10:30am|S-101

In this work we study the correlation between low-degree GF(2) polynomials and explicit functions, where the correlation between two functions f,p : {0,1}^n -> {+1,-1} is defined as Correlation(p,f) := | E_x [f(x) p(x)] | = | P_x[f(x) = p(x)] - P_x...

New Locally Decodable Codes and Private Information Retrieval Schemes
11:15am|S-101

A q-query Locally Decodable Code (LDC) encodes an n-bit message x as an N-bit codeword C(x), such that one can probabilistically recover any bit x_i of the message by querying only q bits of the codeword C(x), even after some constant fraction of...

A New Approach to Universality Limits Involving Orthogonal Polynomials
Doron Lubinsky
1:30pm|S-101

We present a new approach to some of the universality limits that arise in orthogonal polynomials. For example, we show that if w is a fixed weight positive a.e. in [-1,1], and w satisfies a Dini condition in some subinterval of (-1,1), then there...
