TOPOLOGY/ GEOMETRY SEMINAR
TITLE: Compactifications via ultrafilters
SPEAKER: Jerzy Dydak, University of Tennessee
TIME: 3:35 PM-4:25 PM
ROOM: Ayres 406
I will discuss constructing compactifications using ultrafilters and applying the following result from the book "Geometric group theory" (Cornelia Drutu and Michael Kapovich):

Lemma 1.18. [Extension lemma] Suppose that X,Y topological spaces, where Y is regular and X contains a dense subset A.

1. If f : X to Y is a mapping satisfying the property that for each x in X the restriction of f to A union {x} is continuous, then f is continuous.

2. Assume now that A is open and set X\A=Z. Suppose that f:X to Y is such that the restriction f to A union {z} is continuous at z for every point z in Z. Then f:X to Y is continuous at each point z of Z.

A proof of the lemma will be presented.

Tuesday, 9/11

STOCHASTICS/PROBABILITY SEMINAR
TITLE: Ergodicity and large deviations for two kinds of fluid mechanics driven by stochastic forcing
SPEAKER: Rangrang Zhang, Beijing Institute of Technology
TIME: 2:10 PM-3:10 PM
ROOM: Ayres 113
In this talk, I will introduce two equations: viscous stochastic primitive equations and inviscid stochastic scalar conservation laws. The ergodic theory and large deviation principles for the above two models will be presented.

MINIMAL SURFACES SEMINAR
TITLE: Colding-Minicozzi Paper 2-part 1
SPEAKER: Ryan Unger, University of Tennessee
TIME: 4:00 PM-5:30 PM
ROOM: Ayres 121
We will show curvature estimates on embedded minimal disks with bounded total curvature.

Wednesday, 9/12
