Wakulla Springs

I am `Distinguished Research Professor' of mathematics at Florida State University. I was the first Marion Bradley Brennan Professor in the department. I am also a frequent visitor of Caltech, and one of the managing editors of the Journal of Singularities, a publication of the Worldwide Center of Mathematics.
My research is in Algebraic Geometry. This is my mathematical lineage, according to the Mathematics Genealogy Project. Here is some recent work:

• Explicit formulas for the Grothendieck class of M0n-bar, with Matilde Marcolli and Eduardo Nascimento, 31 pages, arXiv:2406.13095.
  
• Log concavity of the Grothendieck class of M0n-bar, with Stephanie Chen and Matilde Marcolli, 17 pages, arXiv:2402.02646.
  

I have written two introductory textbooks in abstract algebra: Algebra: Chapter 0 and Algebra: Notes from the Underground. There are truckloads of typos and more serious mistakes in both texts.

• List of errata for the first printing of Algebra: Chapter 0.
  List of errata for the second printing.

  Note: The second printing incorporates the errata to the first printing through 2015. If you run into this book and want to know which version it is, look for a "Preface to the second printing" on p. xv. If it is not there, the version you are looking at is the first printing. If it is, you are looking at the second printing.
