PROBABILITY SEMINAR
TIME: 10:10 11:00 a.m.
ROOM: AC 113
SPEAKER: Professor Xiangdong Liu, Jinan University, China
TITLE: The Multifactor Term Structure of Interest Rates under Regime Shifts
and Levy Jumps
ABSTRACT: We develop a general dynamic term structure models under jump-diffusion
with Levy Jumps and regime shifts with time varying transition probabilities.
The model allows for regime-dependent jumps with jump risk and regime-switching
risk. We study the bond pricing problem of this model under pseudo-affine structure
and derive two types solutions: approximation(log-linear) solution and exact
solution under diferent conditions. Furthermore for a special case, when the
underlying process has two regimes and double Gamma jumps, we obtain a closed
form expression for bond prices.
TOPOLOGY SEMINAR
TIME: 11:15 12:05 p.m.
ROOM: Temple 303
SPEAKER: Dr. Stella Huerfano
TITLE: "Khovanov type homologies and extended (1+1)-TQFT's II"
ABSTRACT: It will be explained how different Frobenius and Knowledgeable Frobenius
Algebras define invariants for tangles analogous to the Khovanov homology groups.
Furthermore it will be explained how these algebraic structures define extended TQFT's.
Bread situation: severe shortages due to production interruptions (conference in MS).

DOCTORAL DEFENSE
TIME: 2:30 p.m.
ROOM: Temple Court 303
SPEAKER: Mr. Brian Irick
TITLE: On the Irreducibility of the Cauchy-Mirimanoff Polynomials
His committee consists of Professors: Tzermias (chair), Dobbs, Mulay, and Sorensen
(Physics).
Wednesday, March 31
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 V
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.
