DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UAANTS/11/">
 Some Breuil-Mezard identities in moduli spaces of Breuil-Kisin modules</a>
 \nby Robin Bartlett (Univ. of Münster) as part of University of Arizona A
 lgebra and Number Theory Seminar\n\n\nAbstract\nThe Breuil--Mezard conject
 ure predicts certain identities between cycles in moduli spaces of mod p G
 alois representations in terms of the Fp-representation theory of GLn(Fq).
 \n\nIn this talk I will discuss work in progress which considers the situt
 ation arising from (the reduction modulo p of) two dimensional crystalline
  Galois representation with suitably small* Hodge--Tate weights. We will d
 iscuss how the predected identities can also seen in ``resolutions`` of th
 ese spaces of Galois representations described in terms of semilinar algeb
 ra.\n\n*small will be precisely the bound which ensures that the Fp-repres
 entation theory of GL2(Fq) appearing behaves precisely as it would with ch
 ar 0 coefficients.\n
