Research in Geometry/Topology
Geometry and topology at Berkeley center around the study of manifolds, with the incorporation of methods from algebra and analysis.
The principal areas of research in geometry involve symplectic, Riemannian, and complex manifolds, with applications to and from combinatorics, classical and quantum physics, ordinary and partial differential equations, and representation theory.
Research in topology per se is currently concentrated to a large extent on the study of manifolds in low dimensions. Topics of interest include knot theory, 3- and 4-dimensional manifolds, and manifolds with other structures such as symplectic 4-manifolds, contact 3-manifolds, hyperbolic 3-manifolds. Research problems are often motivated by parts of theoretical physics, and are related to geometric group theory, topological quantum field theories, gauge theory and Seiberg-Witten theory, and higher dimensional topology.
A number of members of the Geometry/Topology group belong to the Research Training Group in Geometry and Topology, which runs activities and supports grad students and postdocs in its areas of interest.

The Topology seminar is held weekly throughout the year, normally
Wednesdays at 4pm. The speakers are normally visitors, but sometimes are
resident faculty or graduate students. Three times a year the Bay Area
Topology Seminar meets at Stanford (fall), Berkeley (winter) and Davis
(spring), with two lectures in the afternoon and dinner afterward.
There are various seminars related to symplectic geometry. On the first Monday of 7 months per year, there is a meeting of the Northern California Symplectic Geometry Seminar (Berkeley-Davis-Santa Cruz-Stanford), with two talks and a dinner, the venue alternating between Berkeley and Stanford. In the first (October) meeting of each academic year, one of the talks is the Andreas Floer Memorial Lecture, given by a distinguished invited speaker.
The Differential Geometry seminar is held weekly throughout the year, normally Mondays at 5.
