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

      • Most people refer to me by my nickname "Bill".
  • Next fall I teach Math 431 (Geometry for Computer Applications), a course I've been developing for many years. In 2021 it was taught by my former doctoral student Justin Wyss-Gallifent.
  • I serve on the faculty of both the MATH and AMSC graduate programs at the University of Maryland and have supervised several doctoral dissertations
  • Recent and upcoming lectures:
  • Selected research projects:
    • 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.
    • A part of the introduction for the Festschrift for Toshiyuki Kobayashi dealing with his work on proper actions in pseudo-Riemannian geometry.
    • Current and past experimental projects

  • Recent Administrative Activities:
    • Member-At-Large of the Council of the American Mathematical Society and member of the Committee on Publications.
    • Brin Mathematics Research Center at the University of Maryland.
      • Member, Scientific Advisory Board.
      • I recently co-organized (with Steve Bradlow and Richard Wentworth) Brin MRC a workshop ``Advances in Higgs bundles." there.
      • Nnext year I will be co-organizing (with Caleb Ashley, Charles Frances, Jill McGowan and Karin Melnick) a workshop ``Affine and hyperbolic geoemetry" in memory of Todd Drumm.
    • Former member (with Patrick Brosnan and Abba Gumel), Department Colloquium Committee.
    • Administrative activities before 2015
    • Network Executive Committee (original co-PI, and director of Maryland hub), GEAR Network, an NSF Research Network in the Mathematical Sciences, 2011-2022; with Steve Bradlow, Steve Kerkchff, Richard Wentworth and Anna Wienhard.
    • Scientific Advisory Board (2020-2022), Institute for Computational and Experimental Research in Mathematics (ICERM), Brown University.
