The Topography of Random Waves
2:00pm|S-101

Random waves have been investigated since the 1940's in connection with modeling telephone signals (Rice), to model sea waves (Longuet-Higgins), and since the 1970's by Berry and others to model quantum wave-functions of classically chaotic systems...

Computer Science/Discrete Mathematics Seminar I

Affine Dispersers from Subspace Polynomials
11:15am|S-101

This talk describes new explicit constructions of dispersers for affine sources of dimension below the notorious n/2 threshold. The main novelty in our construction lies in the method of proof which relies (solely) on elementary properties of...

Dynamical Mordell-Lang Problems
Thomas J. Tucker
4:30pm|West Bldg. Lecture Hall

The Mordell-Lang conjecture, proved by Faltings and Vojta, states that a finitely generated subgroup of a semiabelian variety intersects any subvariety of that semiabelian variety in a union of finitely many translates of subgroups. It seems natural...
