Computer Science/Discrete Mathematics Seminar I

Towards Harmful Low-Rate Noise Models for Quantum Computers
11:15am|S-101

We propose and discuss two conjectures on the nature of errors in highly correlated noisy physical stochastic systems. The first asserts that errors for a pair of substantially correlated elements are themselves substantially correlated. The second...

A Weyl-like bound for automorphic L-Functions
4:30pm|S-101

A central problem in the theory of L-functions is to investigate their sizes on the critical line. The convexity bound, which follows from the Phragmen-Lindelof principle, is of little use in applications. Therefore much effort has been made to...

Birational Geometry

Finite Generation II
Micea Mustata and Nero Budur
1:00pm|S-101

We start by stating the general form of the Minimal Model Conjecture and explain the relevance of some recent work of Bouksom-Demailly-Paun-Peternell. After that we describe the general picture of the proof of Hacon et al for the general type case.

Fundamental Lemma

Moduli of Metaplectic Bundles on Curves and Theta-Sheaves
10:30am|S-101

We give a geometric analog of the Weil representation of the metaplectic group, placing it in the framework of the geometric Langlands program. For a smooth projective curve X we introduce an algebraic stack \tilde\Bun_G of metaplectic bundles on X...

Critical 2d Models on the Annulus
John Cardy
2:30pm|S-101

I conjecture a form for the scaling limit of the partition function of the critical O(n) and Potts models on the annulus, using Coulomb gas methods. This has several subtleties whose elucidation sheds light on the nature of the Coulomb gas mapping.

Complex Algebraic Geometry

Locally Residual Currents and Dolbeault Cohomology on Projective Manifolds
1:00pm|S-101

First we define, for any analytic manifold $X$ of dimension $n$, locally residual currents; $C^{q,p}$ denotes the sheaf of locally residual currents of bidegree $(q,p)$. Then, we have a fundamental resolution of the sheaf of holomorphic $q-$forms $...

2-Source Dispersers for Sub-Polynomial Min-Entropy and Ramsey Graphs Beating the Frankl Wilson Construction
10:30am|S-101

The main result of this work is an explicit disperser for two independent sources on $n$ bits, each of entropy $k=n^{o(1)}$. Put differently, setting $N=2^n$ and $K=2^k$, we construct explicit $N \times N$ Boolean matrices for which no $K \times K$...

2-Source Dispersers for n^{o(1)} Entropy, and Ramsey Graphs Beating theFrankl-Wilson Construction
11:15am|S-101

The main result of this work is an explicit disperser for two independent sources on n bits, each of entropy k=n^{o(1)}. Put differently, setting N=2^n and K=2^k, we construct explicit N by N Boolean matrices for which no K by K submatrix is...
