WILLIAM GOLDMAN
    I am Professor in the Mathematics Department at the University of Maryland.

      • Most people refer to me by my nickname "Bill".
  • I recently spoke at the annual Maryland Dynamics Conference. See my slides .
  • Here is a recent preprint discussing how the deformation space of complete affine 2-manifolds relates to a twisted cubic cone in 4-space. This result was suggested by Pierre Deligne after I mentioned it in a lecture I gave at the Institute for Advanced Study during my 2021 sabbatical there. It gives an explicit proof of Oliver Baues's theorem that this deformation space is homeomorphic to a plane. This paper will appear in a Contemporary Mathematics volume celebrating Ravi Kulkarni's 80th birthday.
  • My first paper with my colleague Giovanni Forni, Mixing Flows on moduli spaces of flat bundles over sruraces appeared in Volume 2 of ``Geometry and Physics,'' dedicated to Nigel Hitchin's 70th birthday conferences in Oxford, Aarhus and Madrid. (I could only attend the conference in Oxford.) This paper outlines a program to study dynamical problems arising from the classification of geometric structures on manifolds by introducing a cocycle of symplectic moduli spaces over the Teichmueller geodesic flow and SL(2,R)-action.
  • I am currently investigating a remarkable family of real affine cubic surfaces which arise as relative SL(2)-character varieties for a one-holed torus. See if you can run the interactive Mathematica notebook I wrote with Ajeet Gary several years ago.
  • I am currently teaching ``Fudamental Concepts of Differential Geometry, (MATH740) which meets Tuesdays-Thursday at 11:00 in MTH1311.
  • I serve on the faculty of both the MATH and AMSC graduate programs at the University of Maryland and have supervised several doctoral dissertations.
  • Co-director (with Rodrigo Trevino), Lab for Experimental Mathematics at MAryland (LEMMA). I cofounded this experiment with Richard Schwartz in 2000, when it was called the Experimental Geometry Lab. You can read about it here. I was one of the founding members of Geometry Labs United, and co-organized the Geometry Labs United Conference which took place at ICERM, 16-17 July 2020.
