Correlation of magic sequences and some ideas from outer space
6:00pm|Dilworth Room

Magic sequences were introduced for the first radar measurements of the distance to Venus. They are now used in GPS, satellite and cell phone communications. In many cases their correlation properties can be determined using some crazy ideas of...

Non-equilibrium Dynamics and Random Matrices

The Brownian motion as the limit of a deterministic system of hard-spheres
Thierry Bodineau
2:00pm|S-101

We provide a derivation of the brownian motion as the hydrodynamic limit of a diluted deterministic system of hard-spheres (in the Boltzmann-Grad limit). We use the linear Boltzmann equation as an intermediate level of description for one tagged...

Non-equilibrium Dynamics and Random Matrices

The Sherrington-Kirkpatrick model and its diluted version II
Dmitry Panchenko
11:00am|S-101

I will talk about two types of random processes -- the classical Sherrington-Kirkpatrick (SK) model of spin glasses and its diluted version. One of the main goals in these models is to find a formula for the maximum of the process, or the free...

How to Delegate Computations: The Power of No-Signaling
10:30am|S-101

The Martians built an amazingly fast computer and they run it to answer the great question of life, the universe and everything. They claim that the answer is 42. Will they be able to convince us that this is the right answer, assuming that we do...

Filtering the Grothendieck ring of varieties
2:00pm|S-101

The Grothendieck ring of varieties over \(k\) is defined to be the free abelian group generated by varieties over \(k\), modulo the relation \([X] = [Y] + [X \backslash Y]\) for all \(X\) and closed subvarieties \(Y\). Multiplication is induced by...

Two Structural Results for Low Degree Polynomials and Applications
11:15am|S-101

In this talk we will present two structural results concerning low degree polynomials over \(GF(2)\). The first states that for any degree d polynomial \(f\) in \(n\) variables over \(GF(2)\), there exists a subspace of \(GF(2)^n\) with dimension \(...
