PROBABILITY SEMINAR
TIME: 10:10 – 11:00
ROOM: Temple 303
SPEAKER: Mr. Matt Turner
TITLE: "Ito isomorphisms for stochastic integrals driven by Levy processes with applications. Part II."
ABSTRACT: We give explicit bounds for the p-th absolute moments of infinitely divisible distributions in terms of Orlicz-type mixed moments of Levy measures. This result is needed to establish Ito-type isomorphisms for stochastic integrals driven by Levy processes, which will be presented in the later parts of the talk.
ALGEBRA SEMINAR
TIME: 3:35 – 4:25 pm
ROOM: AC 113A
SPEAKER: Mr. Vajira Manathunga
TITLE: "Noncommuting graph of a group" (Part 3)
ABSTRACT: The noncommuting graph T(G) of a non-abelian finite group G is define as follows. The vertices of T (G) are represented by the M<>?M<>?M<>?M<>?M<>?M<>?M<>? noncentral elements of G, and two distinct vertices are joined by an edge if they do not commute. We will begin with a brief introduction to noncommuting graphs of a group. Next we consider the following question: Let G and H be two non-abelian finite groups whose noncommuting graphs are isomorphic. Then is |G|=|H|? We will illustrate the counterexample given by A.R.Moghaddamfar in "About Noncommuting Graphs", Siberian Math. J., 47, No. 5, 911-914 (2006).
