Perverse Sheaves & the Decomposition Theorem

Working Seminar Winter 2016

The aim of this working seminar is to give an introduction to Intersection (Co)Homology, Perverse Sheaves, the Decomposition Theorem, and end up with a tour of some classical and modern applications and conjectures. We will try to develop as much as possible "ground up", so no particular pre-knowledge is assumed.


All talks taking place Tuesdays, 1-2pm, in JCMB 5326.

  • F. Kirwan and J. Woolf, An introduction to intersection homology theory. Second edition. Chapman & Hall/CRC, Boca Raton, FL, 2006. Book website.
  • Georgie Williamson, An illustrated guide to perverse sheaves, unpublished notes, available online.

Other useful references will be pointed out during the semester.
