DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QMULANTS/17/
 ">Breuil-Mezard identities in moduli spaces of Breuil-Kisin modules</a>\nb
 y Robin Bartlett (Munster) as part of Queen Mary University of London Alge
 bra and Number Theory Seminar\n\n\nAbstract\nThe Breuil-Mezard conjectures
  predicts relations between certain cycles\nin the moduli space of mod p G
 alois representations\, in terms of the representation\ntheory of GLn(Fq).
 \n\nIn this talk I will consider the special case where the cycles in ques
 tion come from\ntwo dimensional crystalline representations with small Hod
 ge-Tate weights. Under\nthese assumptions I will explain how the topologic
 al aspects of these identities can\nbe obtained from analagous identities 
 appearing\, first inside the affine\nGrassmannian\, and then in moduli spa
 ces of Breuil-Kisin modules.\n
