Department of Mathematics and Statistics Talks for the week March 16-20, 2009 (previous week)

Analysis Seminar: "Two Applications of Large Deviations"   Date Monday, March 16, 2009 Time 4:00 pm – 5:00 pm CDT Where Room G-4, Rolla Building Event Type Lectures & Seminars Presenter Dr. Sastri Chelluri Sponsored by Department of Mathematics and Statistics Contact David Grow Description The seminar will present a brief survey of the main ideas of large deviations. Two applications will then be discussed, one involving a sequence of i.i.d. random variables and the other discussing weakly dependent random variables. The proofs of some of the basic theorems were presented in a series of talks last year and will not be repeated, although references will be given. Topology/Algebra Seminar: "Sheaves and sheaf cohomologies (cont.)"   Date Thursday, March 19, 2009 Time 4:00 pm – 5:00 pm CDT Where Room G-5, Rolla Building Event Type Lectures & Seminars Presenter Malgorzata Marciniak Sponsored by Mathematics & Statistics Department Contact Robert Roe Description The lecture will present definitions of a sheaf, a presheaf and their properties with emphasis on the sheaf of germs of holomorphic functions, followed by a discussion of the basic ideas of the sheaf-theoretic cohomology theory with supports.
