Week of November 1 - 5

Tuesday, November 2

 2:30 ALGEBRA SEMINAR  - Room 447 MSC
      Steve McCleary, Mathematics and Statistics, BGSU
      "Lattice-ordered permutation groups, Part VII"
      This is the seventh (and hopefully last) in a series of talks.

 2:30 SCIENTIFIC COMPUTATION SEMINAR  - Room 459 MSC
      Neal Carothers, Mathematics and Statistics, BGSU
      "Details from Daubechies, Part III"
      Abstract: This talk will use Fourier transform techniques to
        outline the proof of the existence of the "mother wavelet"
        which is orthogonal to the scaling function and whose
        translates and dilates are mutually orthogonal.

Wednesday, November 3

 2:30 ANALYSIS SEMINAR  - Room 459 MSC
      Kit Chan, Mathematics and Statistics, BGSU 
      "Essential spectra"

Thursday, November 4

 1:30 LUKACS LECTURE  - Room 400 MSC
      Raju Govindarajulu, Distinguished Lukacs Professor, BGSU and
                          University of Kentucky
      "Bioassay: estimation of LD50 (or ED50)"

Friday, November 5

 1:30 LUKACS LECTURE  - Room 400 MSC
      Raju Govindarajulu, Distinguished Lukacs Professor, BGSU and
                          University of Kentucky
      "The secretary problem (optimal stopping problem)"
      This will be a two-hour talk, and the last in the series of
      Lukacs Lectures by Professor Govindarajulu.

      Zhimin Zhang, Wayne State University
      "Large finite element superconvergence in computational mathematics"
      Abstract: It was found that the rate of convergence of finite
        element approximations exceeds the optimal global rate at some
        exceptional global points. This phenomenon is called
        "superconvergence" and these special points are called
        "natural superconvergence points."  Most earlier works on
        superconvergence were concentrated on tensor-product
        rectangular elements and lower order (linear and quadratic)
        triangular elements. In this work, a systematic method is
        introduced, analyzed, and used to find all gradient
        superconvergent points of arbitrary rectangular finite
        elements. The results justify some computer findings.  The
        method is then generalized to three dimensional elements to
        predict gradient superconvergence points which have not been
        reported in the literature.
