SUMMARY:p-Kazhdan- Lusztig theory - Chris Bowman-Scargill  (York)
DTSTART:20221019T153000Z
DTEND:20221019T163000Z
UID:TALK183017@talks.cam.ac.uk
CONTACT:Christopher Brookes
DESCRIPTION:We will discuss recent results in modular Lie theory obtained 
 in the setting of "diagrammatic Hecke categories”.  We will discuss the 
 Kazhdan-Lusztig positivity conjecture\, the counter examples to Lusztig’
 s conjecture\, and how p-Kazhdan-Lusztig polynomials can be seen to contro
 l the representation theory of braid groups\, cyclotomic Hecke algebras\, 
 and algebraic groups.  We also discuss when these polynomials can and cann
 ot be explicitly calculated.
