Automorphism Groups of Surface Cluster Algebras

Series
Geometry Topology Student Seminar
Time
Thursday, July 16, 2015 - 14:05 for 1 hour (actually 50 minutes)
Location
Skiles 006
Speaker
Shane Scott – Georgia Tech –
This talk is an oral comprehensive exam in partial fulfillment of the requirements for a doctoral degree. To any topological surface we can assign a certain communtative algebra called a cluster algebra. A surface cluster algebra naturally records the geometry of the surface. The algebra is generated by arcs of the surface. Arcs carry a simplicial structure where the maximal simplices are triangulations. If you squint you can view a surface cluster algebra as a coordinate ring of decorated Teichmuller space with Penner's coordinate. Recent work from many authors has shown that the automorphisms of the surface cluster algebra which preserve triangulations arise from the mapping class group of the surface. But there are additional automorphisms that preserve meaningful structure of the cluster algebra. In this talk we will define surface cluster algebras and discuss future research toward understanding structure preserving automorphisms.

MCTP REU Seminar: Elevating Deceptions: A Mathemagical Mystery Tour

Series

Time
Friday, June 26, 2015 - 11:00 for 1 hour (actually 50 minutes)
Location

Speaker
Dr. Matt Baker – Georgia Institute of Technology
Science explains through systematic inquiry; magic celebrates that which defies explanation. This will be tour of sorts along the boundary between science and magic. We will explore the magic of quantum mechanics, the predictions of knot theory, and randomness, as well as the mysteries of the number 58008.

Analytic Continuation of Analytic Fractals

Series
Analysis Seminar
Time
Wednesday, June 24, 2015 - 15:00 for 1 hour (actually 50 minutes)
Location
Skiles 005
Speaker
Michael Barnsley – Mathematical Sciences Institute, Australian National University
Examples of analytic fractals are Julia sets, Koch Curves, and Sierpinski triangles, and graphs of analytic functions. Given a piece of such a set, how does one "continue" it, in a manner consistent with the classical construction of an analytic Riemannian manifold, starting from a locally convergent series expansion?

MCTP REU Seminar -Reaction Diffusion Equations and Pattern Formation in Mathematical Biology (How the Zebra got his/her stripes)

Series
Other Talks
Time
Monday, June 22, 2015 - 12:00 for 1 hour (actually 50 minutes)
Location
Skiles 006
Speaker
Dr. James Moore – Georgia Institute of Technology
Reaction diffusion equations are a common tool in mathematical biology, and are used in diverse fields such as ecology, epidemiology and developmental biologyI will show some examples of reaction diffusion equations and what their solutions look like. I will focus on the problem of pattern formation during development and the mathematics that underly it, a problem first studied by Alan Turing more than 60 years ago. I will present a basic example that we can solve together using techniques from differential equations and linear algebra.

MCTP REU Seminar: Riddles about the fundamental group

Series
Other Talks
Time
Friday, June 19, 2015 - 11:00 for 1 hour (actually 50 minutes)
Location
Skiles 006
Speaker
Dr. Kirsten Wickelgren – Georgia Tech
The loops on a topological space up to an equivalence relation called homotopy form a group called the fundamental group. We'll define the fundamental group and talk about two riddles whose solutions use this idea.

On the marginals of product measures

Series
Stochastics Seminar
Time
Monday, June 15, 2015 - 14:00 for 1 hour (actually 50 minutes)
Location
Skiles 005
Speaker
Galyna Livshyts – Kent State University
It was shown by Keith Ball that the maximal section of an n-dimensional cube is \sqrt{2}. We show the analogous sharp bound for a maximal marginal of a product measure with bounded density. We also show an optimal bound for all k-codimensional marginals in this setting, conjectured by Rudelson and Vershynin. This talk is based on the joint work with G. Paouris and P. Pivovarov.

Workshop on Writing a Teaching Philosophy Statement

Series
Professional Development Seminar
Time
Friday, June 12, 2015 - 15:00 for 1 hour (actually 50 minutes)
Location
Skiles 005
Speaker
Helen G. Grundman – Bryn Mawr College
A teaching philosophy statement is an crucial part of your dossier. This will be a participatory workshop designed to help you write a statement of your teaching philosophy -- one that accurately reflects your personal beliefs and attitudes. We will begin with some simple exercises to help you identify what you feel is important about teaching in general and your teaching in particular. We will discuss how to translate the outcomes of these exercises into a coherent statement. With luck, there will also be plenty of time for questions. (Please bring paper and something to write with (or a laptop or tablet).)
