                         Week of December 2-6

Monday, December 2

 3:30 PM  MAPLE WORKSHOP  - SciCompLab on the classroom (south) side
          John Gresser, Dept. of Mathematics and Statistics, BGSU.

Wednesday, December 4

 3:00 PM  ANALYSIS SEMINAR  - Room 459 MSC 
     **** Note change in time ****
          Kit Chan, Dept. of Mathematics and Statistics, BGSU. 
          "Wiener's 1/f theorem"
          Abstract: One of Wiener's famous theorems states that if
            f(x) has an absolutely convergent Fourier series and never
            vanishes, then 1/f has an absolutely convergent Fourier
            series.  Without using Gelfand theory, two elementary
            proofs for this theorem have been found by D. J. Newman
            and J. Spilker.  I will present these two interesting
            proofs, and also an extension found by M. von Renteln to n
            functions.  All graduate students are welcome.

 4:00 PM  PHYSICS AND ASTRONOMY COLLOQUIUM  - Room 106 Overman
          Hung T. Huynh, NASA Lewis Research Center, Cleveland, OH
          "A simple upwind scheme"
          Abstract: Upwind schemes are currently popular in
            Computational Fluid Dynamics, Astrophysics, Hydrodynamics,
            Solid Mechanics ... These schemes are generally perceived
            as difficult to formulate and implement. In this talk, I
            will present a simple upwind scheme. The ingredients are:
            the midpoint rule, a linearization, a diagonalization, and
            the mean value theorem. I will also discuss a few open
            problems related to upwind methods.

Thursday, December 5

 1:30 PM  SCIENTIFIC COMPUTATION SEMINAR  - Room 459 MSC
          Comer Duncan, Dept. of Physics and Astronomy, BGSU.
          "A hyperbolic solver for vacuum axisymmetric spacetimes:
          the method and weak gravitational wave tests"
          Second talk.

          Abstract: A discussion of some experiences, ideas, opinions,
            and principles involved in developing a supportive
            environment for learning mathematics.
