Thalia Jeffres, Associate Professor

Differential Geometry; PhD, SUNY at StonyBrook, 1996




Dr. Jeffres' field of investigation is Riemannian and complex differential geometry. In particular, she is interested in special metrics on manifolds that are noncompact or which have singularities. Special metrics are those for which some curvature is constant. Since the curvature is an expression in the derivatives of the metric, setting this equal to a constant yields a partial differential equation. Therefore, solution of these problems frequently also involves some PDE techniques. Related to this, Dr. Jeffres is also interested in the heat operator.
