The geometry seminar is typically held every Monday in term time at 2pm, in the Salle des Profs (9th floor, building NO). 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.
