  Currently Teaching Course:

  
  Fall Semester 2009 Math 115 - Calculus I

  Research Interests:

  My mathematical interests are in general topology specializing in extensions and absolutes of Hausdorff spaces. Here at the University of Kansas we have a very active group in applied set theory and general topology. The other permanent faculty members in this group are Judy Roitman roitman@math.ku.edu and Bill Fleissner fleissner@math.ku.edu. We usually have some advanced graduate students and often have post-docs in this group, have an active seminar and have several outside speakers visit each year.

  Some of my Publications:

  • Cardinalities of H-closed spaces, Topology Proc., 7 (1982), 27-50. (with A. Dow).
  • Embedding in R-closed spaces, Topology and its Appl., 15 (1983), 45-58 (with A. Dow).
  • Spaces with coarser minimal Hausdorff topologies, Trans. Amer. Math. Soc., 289 (1985), 59-71. (with J. Vermeer).
  • On Katetov spaces, Canad. Math. Bull., 32(2) (1989), 425-433. (with M. Tikoo).
  • Tychonoff embedding, Recent Developments of General Topology and its Applications, Proc 1992 International Conference in Memory of Felix Hausdorff, Berlin, Germany Mathematical Research 67 (1992), 261-267.
  • Extensions of discrete spaces, Proc. 1991 Summer Conference on Topology, Madison, Wisconsin, New York Academy of Sciences 704 (1993), 290-296.
  • Subspaces of connected spaces, Topology and its Applications 68 (1996), 113-131. (with R. G. Woods).

  Book:

  Extensions and Absolutes of Hausdorff Spaces, Springer-Verlag, 1987. (with R. G. Woods)

  GEORGE SANTAYANA:Those who cannot remember the past are condemned to repeat it.
  
  FRANCIS BACON: He that will not apply new remedies must expect new evils; for time is the greatest innovator.
  
  GALILEO:The great book of nature can be read only by those who know the language in which it is written, and this language is mathematics.
  
  ALBERT EINSTEIN: In the middle of difficulties lies opportunity.
  
  From the Cherokee Web Site: Do not dismiss your dreams. To be without dreams is to be without hope. To be without hope is to be without purpose.
  
  ROBERT FROST:The woods are lovely, dark and deep, But I have promises to keep, And miles to go before I sleep, And miles to go before I sleep
  
  MARK TWAIN: Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.
