TOPOLOGY/GEOMETRY SEMINAR
TITLE: Asymptotic dimension for non-metric spaces II
SPEAKER: Ryan Jensen, UTK
TIME: 2:30pm – 3:20pm
ROOM: Ayres 114
We will continue talking about asymptotic dimension. For coarse metric spaces, there are several useful definitions, which were assembled and shown to be equivalent by G. Bell and A. Dranishnikov.  In this talk, we generalize some of these definitions to non-metric coarse spaces. We begin by giving some needed background information concerning coarse spaces. Next we state a definition, originally by J. Dydak and {\v{Z}}. Virk, of asymptotic dimension suitable for non-metric spaces. Finally we extend a result of J. Dydak and {\v{Z}}. Virk, which will give another definition of asymptotic dimension for non-metric spaces.

MATH BIOLOGY SEMINAR
TITLE: Speed of invasion in lattice population models: pair-edge approximation
SPEAKER: Shelby Scott, UTK
TIME: 2:30pm – 3:20pm
ROOM: Ayres G003

ALGEBRA SEMINAR
TITLE: Properties of the set of continuous functions from a compact Hausdorff space to a topological field
SPEAKER: Pawel Grzegrzolka, UTK
TIME: 3:35pm – 4:25pm
ROOM: Ayres 113
The study of continuous functions between two topological spaces is considered to be one of the fundamental interests in topology. However, the study of such functions arises in other branches of mathematics, including abstract algebra. In this talk, we will consider continuous functions between a compact Hausdorff space and a topological field. We will prove that under mild conditions on our spaces, the set of such continuous functions satisfies very interesting properties; in particular, we will show that such set of continuous functions from a compact Hausdorff space to the field of real numbers is a ring whose space of maximal ideals is homeomorphic to the real line.


Tuesday, November 22nd


STOCHASTICS SEMINAR
TITLE: Isomorphism identities for perturbed infinitely divisible processes, Part II
SPEAKER: Jan Rosinski, UTK
TIME: 2:10pm – 3:25pm
ROOM: Ayres 114
We consider infinitely divisible processes perturbed by an additive independent noise. We study admissible perturbations under which the perturbed process, which need not be infinitely divisible, is absolutely continuous with respect to the unperturbed process. The Dynkin's isomorphism theorem is an example of such phenomenon, where the local time of a Markov process is the perturbation.
