Research & Service
"Thought must never be subordinated to any dogma, political party, passion, interest, preconceived idea, to anything indeed, except
the facts themselves, because, for science, to
be subordinated means
to die."
Henri Poincaré
My interests include real algebraic geometry and ordered algebraic structures. Here is some recent work:
Composition-closed l-groups. Top. and its App. 2011.
Mel Henriksen. Top. and its App. 2011.
Varieties of f-rings. Alg. Univ. 2010.
Quotas, walks and socks. Unpublished 2010.
H-closed monoreflections. Top. and its App. 2006.
Peculiar ways to order a ring. Lect. notes, Univ. Paris 7, 2004.
Infinitely near points. Lect. notes, Univ. Angers, 2004.

I am also interested in supporting K-12 educators; see the links to LaMSTI above; also see MathVision Lab. I have posted some resources for teachers of teachers at the Secondary Math Site. Some of my early thoughts about math reform (circa 1996) are here. Some other downloadable stuff (not up-to-date) is here.

"The Edge... there is no honest way to explain it because the only people who really know where it
is are the ones who have gone over."

Concept and drawings by my daughter, Calina.

Other fun...
I was a guest in Sonali's first-grade class in March 2002. She drew me a nice thank-you picture.
The meaning of sine and cosine.

Fun with watermelons in downtown Baton Rouge:

NOT fun...
  What Katrina did to Leoneard's (my brother-in-law's) house in Covington.
  What happened to my Honda Element. (Dry grass, hot catalytic converter.)
