In this talk, I will discuss the solution to several problems in two closely related settings: set families in 2^[n] with many disjoint pairs, and low-rank matrices with many zero entries.

Highlights include a resolution of an old question of Daykin...

This semester, we will be beginning a *very informal* get-together every Monday of people interested in/working on phenomenology and new theories beyond the standard model.  The idea is to discuss over lunch, perhaps meet up around 12.20, grab lunch...

Abstract: With only one joint gravitational wave (GW)-electromagnetic (EM) detection to date, observations of the EM counterparts to neutron star mergers are a key path to probing the physics of these unique systems and predicting the behavior of...

In probability theory, universality is the phenomenon where random processes converge to a common limit despite microscopic differences. For instance, the random walk, under mild conditions, converges to the same Brownian motion seen from afar...

Abstract:  In gauge theories with Chern-Simons interactions, the Gauss law -- the requirement that physical states be gauge invariant -- implies that the quantum wavefunction is naturally a section of a nontrivial line bundle over the space of...

Let $X/S$ be a regular scheme over the spectrum of a discrete valuation ring. Bloch conjectured a formula relating algebraic differential forms to the total dimension of the vanishing cohomology of $X/S$. In this talk, I will explain a proof of this...

We propose an extension of Yao's standard two-party communication model, where Alice and Bob respectively hold probability distributions p and q over inputs to a function f, rather than singleton inputs. Their goal is to estimate E[f(x,y)] to within...
