The geometry seminar is held roughly every two weeks in term time. We invite speakers with a broad range of expertise, from all areas of differential geometry, algebraic geometry and geometric analysis. If you would like to suggest a speaker, give a talk yourself, or want any further information about the seminar then contact any of the professors in the geometry group.

The schedule for the current term is below. (When a title is a link, clicking it will take you to the abstract.)
