Geometry Tea

Geometry Tea is the junior geometry seminar series in Cambridge covering all aspects of geometry. It's usually given by PhD students or postdocs. Talks usually take place on Fridays in MR13 at 3pm at the faculty of mathematics, and are followed by tea and biscuits in the Pavilion E common room. If you would like to give a talk or invite a speaker please contact me at col24 (at) Expenses can be provided by the department for external speakers, roughly on the level of travel from London.
