# King's Analysis Seminar

## The King's College London Analysis seminar

The KCL analysis seminar is dedicated to all fields of mathematical analysis, from nonlinear PDEs to spectral theory, from probabilty theory to geometric analysis. It takes place on Thursdays at 11AM, KCL Strand Building, Room S5.20. If you want to be added to the mailing list contact one of the organisers: Jean Lagacé or Felipe Marceca (in either case, firstname.surname@kcl.ac.uk).
