Speaker: Jeffery Kuan, Columbia

Title: Universality questions for the (2+1)--dimensional AKPZ class

Abstract: We consider the (2+1)--dimensional Anisotropic Kardar-Parisi-Zhang (KPZ) universality class, which is a variant of the (1+1)--dimensional KPZ class. Several models, arising from random matrices, representation theory, and non--commutative probability, lead to conjectures for the scaling exponents and limiting distribution.

Geometry Seminar

Time: 3:00PM - 4:00PM

Location: BLOC 628

Speaker: Christopher O'Neill, UC Davis

Title: Random numerical semigroups

Abstract: A numerical semigroup is a subset of the natural numbers that is closed under addition. Consider a numerical semigroup S selected via the following random process: fix a probability p and a positive integer M, and select a generating set for S from the integers 1,...,M where each potential generator has probability p of being selected. What properties can we expect the numerical semigroup S to have? For instance, how many minimal generators do we expect S to have? In this talk, we answer several such questions, and describe some surprisingly deep geometric and combinatorial structures that arise naturally in the process. No familiarity with numerical semigroups or probability will be assumed for this talk.
