PROBABILITY SEMINAR
TIME: 10:10 – 11:00 a.m.
ROOM: AC 113
SPEAKER: Professor Jie Xiong
TITLE: “Large deviation principle for diffusion processes under a nonlinear expectation”
ABSTRACT: Motivated from the study of mathematical finance, we establish a
large deviation principle of the Freidlin-Wentzell type under nonlinear probability for diffusion processes with a small diffusion coefficient. We extend and provide a new proof for a variational identity of Bou\'e and Dupuis which is widely used in deriving the large deviation principle under classical linear probability. Navier-Stokes equation plays an important role in our deriving the large deviation result.
TOPOLOGY SEMINAR
TIME: 11:15 – 12:05 p.m.
ROOM: Temple 303
SPEAKER: Dr. Stella Huerfano
TITLE: "Frobenius Extensions in relation to TQFT's and Khovanov Type Homologies: an overview II"
ABSTRACT: After reviewing the definition of a TQFT (Topological Quantum Field Theory), some examples of Homologies of Khovanov type will be given for certain Frobenius systems.
Wednesday, March 17
COARSE GEOMETRY SEMINAR
TIME: 11:15 – 12:05 p.m.
ROOM: Temple 303
SPEAKER: Mr. Chad Kilpatrick
TITLE: “Property A is Equivalent to Nuclearity and Exactness for Countable
Discrete Groups G” IV
ABSTRACT: In this talk, we will see that for a countable discrete group G, property A is equivalent to:
1. Cr*(G) is exact
2. Cu*(G) is nuclear
3. Cu*(G) is exact.
Here, a C*-algebra A is defined to be nuclear if for any finite subset F of A, the identity map may be approximated on F by unital completely positive maps which factorize through Mn(C), for some n. In this talk, I closely follow Ch. 4: "Connections with C*-Algebras” from
Rufus Willet’s Some Notes on Property A.
ANALYSIS SEMINAR
TIME: 3:35 – 12:05 p.m.
ROOM: HBB 132
SPEAKER: Mr. Zachary Smith
TITLE: “von Neumann type inequalities and a commutant lifting theorem, 3”
Thursday, March 18
DOCTORAL DEFENSE
TIME: 1:00 p.m.
ROOM: Temple Court 303
SPEAKER: Mr. Gerald Orick
TITLE: “Computational Circle Packing: Geometry and Discrete Analytic Function Theory”
His committee consists of Professors: Stephenson (chair), Collins, Richter, and Papenbrock (Physics).
JUNIOR COLLOQUIUM
(Undergraduate Research Colloquium) ((MURC))
TIME: 3:35 – 4:25 p.m.
ROOM: HBB 102
SPEAKERS: Mr. Michael Roberts and Mr. Michael Horning
TITLE: “From Knoxville, Tennessee to Dresden, Germany”
It turns out that our research results are pretty good and we are going to present them this May at the AIMS 8th International Conference, Dresden, Germany.
Did we do this research in order to travel to Germany for free? Did we do this research to be able to go to a better graduate school? And finally how did we succeed to obtain interesting results which are worth a presentation to a regular session at a very prestigious International Conference.
You are welcome to come and to find out the answers to all these questions.
If you are interested in giving or arranging a talk for one of our seminars or colloquiums, please review our calendar.
If you have questions, or a date you would like to confirm, please contact Dr. Steve Wise.
