 3:30 PM  MAPLE WORKSHOP  - SciCompLab on the classroom (south) side
          John Gresser, Dept. of Mathematics and Statistics, BGSU.
          Topics: 1) Techniques of integration.  It's time to bring
            out lots of new Maple commands.  They're impressive! We
            can use Maple to integrate just like we do with pencil and
            paper.  This can be a useful way for students to study
            integration techniques.  These techniques can be used to
            evaluate some integrals that Maple can't do.  Too bad
            Maple, we can.  2) Sequences and series.  If there is
            time, we'll start work on this topic.

 2:30 PM  ANALYSIS SEMINAR  - Room 459 MSC
          Neal Carothers, Dept. of Mathematics and Statistics, BGSU. 
          "More on the Ergodic Theorem"
          Abstract: We continue with our informal discussion of the
            ergodic theorem, concentrating on a few specific examples.
            In particular, we will outline applications (albeit
            tenuous) to number theory, probability, and Fourier
            analysis.  Time permitting, we may even discuss the
            proofs!

 7:30 PM  KME Guest Speaker  - Room 459 MSC
          Gabor Szekely, Dept. of Mathematics and Statistics, BGSU.
          "Numbers and Letters"

Thursday, November 21

 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"
          
 3:30 PM  ALGEBRA SEMINAR  - Room 459 MSC
          Jack Hayden, Dept. of Mathematics and Statistics, BGSU. 
          "Collineations in finite planes: Can there be a rigid plane?"
          Second talk.

Friday, November 22

 3:30 PM  Coffee
 3:45 PM  COLLOQUIUM  - Room 459 MSC
          Arjun Gupta, Dept. of Mathematics and Statistics, BGSU. 
          "Occam's razor via information criterion"
          Abstract: In this talk I will present an application of the
            Scwartz information criterion (SIC) to testing and
            estimation of multiple covariance change points for a
            sequence of m-dimensional (m > 1) Gaussian random vectors.
            We will estimate the number of change-points as well as
            their location.  The consistency of the estimator is
            proved.  The unbiased SIC is also obtained.  Then
            asymptotic null distribution of the test statistic is
            derived.  The result is applied to the weekly prices of
            two stocks (m=2) from 1990 to 1991, and changes are
            successfully detected.
