Week of September 27 - October 1

Tuesday, September 28

 2:30 ALGEBRA SEMINAR  - Room 447 MSC
      Steve McCleary, Mathematics and Statistics, BGSU 
      "Lattice-ordered permutation groups, Part II"
      Abstract:  This is the second of a series of talks.  These talks
        will begin at the beginning, assuming no knowledge of
        lattice-ordered groups and hardly any knowledge of unordered
        permutation groups.

 2:30 SCIENTIFIC COMPUTATION SEMINAR  - Room 459 MSC
      Craig Zirbel, Mathematics and Statistics, BGSU 
      "An introduction to wavelets, Part II"
      Abstract: This talk will explore the general relation between
        the scaling function and the wavelet, incorporating the ideas
        of multiresolution analysis.  Numerical computation of the
        discrete wavelet transform coefficients and the relation to
        filter banks will be discussed.

        Matlab programs and data files related to last week's talk can
        be obtained at http://www-math.bgsu.edu/~zirbel/wavelets/

        This seminar was organized as a group effort to learn about
        wavelets.  We will more or less follow the book Introduction
        to Wavelets and Wavelet Transforms by C. S. Burrus,
        R. A. Gopinath, and H. Guo.  A few of us have copies that one
        could borrow for short periods.

        Note that the topic of this week's analysis seminar is related.

 2:30 ANALYSIS SEMINAR  - Room 459 MSC
      Neal Carothers, Mathematics and Statistics, BGSU 
      "An introduction to frames, Part II"
      Abstract:  A sequence of vectors in a separable Hilbert space is
        called a frame if it is "similar to" an orthonormal basis (in
        a sense that will be made precise).  Frames arose from the
        study of discrete wavelet transforms and are currently a hot
        research area.  We will continue with a brief introduction to
        the theory as well as the history of frames.

Friday, October 1

 3:30 Refreshments
 3:45 COLLOQUIUM  - Room 459 MSC
      Dror Varolin, University of Michigan
      "The geometry of complex spaces"
      Abstract: We explore various mechanisms which rigidify
        symmetries in complex spaces.  These mechanisms are not
        inherent in the definition of complex spaces, and we will show
        this by looking at some examples.

 1:00 KME PICNIC  - Bellard Shelter, Carter Park, Bowling Green

      The Bowling Green chapter of Kappa Mu Epsilon would like to
      invite you to our picnic, which will be held on Sunday, October
      3rd.  The picnic will begin at 1:00PM with a game of Frisbee
      golf for those who want to participate.  We will be providing
      food (of course), which will be served once the game is over (or
      when we get too hungry to wait).  Please come to have some fun
      with your fellow math majors / minors / graduate students /
      professors!  Anyone is welcome to attend!

      The picnic will be free for members of KME and $1 for
      non-members.  Transportation from campus will be available.  If
      you need a ride, please e-mail sabell@bgnet.bgsu.edu so details
      can be arranged.  If you plan to attend, please e-mail the above
      address or Pam Richardson (pamr@bgnet.bgsu.edu) so that we can
      get a rough estimate of how many people will be there.  Don't
      worry - you can still attend if you don't RSVP!  Please join us
      for this great opportunity to mingle and have some fun!

      In the unfortunate event that the weather should not cooperate,
      the picnic will still be held at an alternate venue (most likely
      the Math Science building).

      Carter Park is located south of BGSU near I-75.  The entrance is
      off of Campbell Hill Road under the Bowling Green water tower.
