Non-equilibrium Dynamics and Random Matrices

Exact formulas for random growth off a flat interface
Daniel Remenik
2:00pm|S-101

We will describe formulas for the asymmetric simple exclusion process (ASEP) starting from half-flat and flat initial data. The formulas are for the exponential moments of the height function associated with ASEP. They lead to explicit formulas for...

A quantitative Brunn-Minkowski inequality and estimates on the the remainder in the Riesz rearrangement inequality
Eric Carlen
2:00pm|S-101

We prove a quantitative Brunn-Minkowski inequality for sets \(E\) and \(K\), one of which, \(K\), is assumed convex, but without assumption on the other set. We are primarily interested in the case in which \(K\) is a ball. We use this to prove an...

Computer Science/Discrete Mathematics Seminar II

Deeper Combinatorial Lower Bounds
Siu Man Chan
10:30am|S-101

We will discuss space and parallel complexity, ranging from some classical results which motivated the study, to some recent results concerning combinatorial lower bounds in restricted settings. We will highlight some of their connections to boolean...

Computer Science/Discrete Mathematics Seminar I

Bi-Lipschitz Bijection between the Boolean Cube and the Hamming Ball
11:15am|S-101

We construct a bi-Lipschitz bijection from the Boolean cube to the Hamming ball of equal volume. More precisely, we show that for all even \(n\), there exists an explicit bijection \(f\) from the \(n\)-dimensional Boolean cube to the Hamming ball of...

Joint IAS/Princeton University Symplectic Geometry Seminar

Lagrangian submanifolds of complex projective space
Michael Usher
1:30pm|Fine 322, Princeton University

First, I will discuss a proof that a Lagrangian torus in \(\mathbb{CP}^2\) arising from a semitoric system described by Weiwei Wu coincides with the image in \(\mathbb{CP}^2\) of Chekanov's exotic Lagrangian torus in \(\mathbb R^4\). I will then...

Complex analytic vanishing cycles for formal schemes
4:30pm|S-101

Let \(R={\cal O}_{{\bf C},0}\) be the ring of power series convergent in a neighborhood of zero in the complex plane. Every scheme \(\cal X\) of finite type over \(R\) defines a complex analytic space \({\cal X}^h\) over an open disc \(D\) of small...

Multi-component KPZ equations
11:00am|S-101

The stochastic Burgers equation (equivalent to the one-dimensional KPZ equation) is a hyperbolic conservation law with random currents. In applications, one often has to deal with several conservation laws, a little explored case. We discuss several...
