DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCSD_NTS/77/
 ">Cohomology of intermediate quotients</a>\nby Romyar Sharifi (UCLA) as pa
 rt of UCSD number theory seminar\n\nLecture held in APM 6402 and online.\n
 \nAbstract\nWe will discuss Galois cohomology groups of “intermediate”
  quotients of an induced module\, which sit between Iwasawa cohomology up 
 a tower and cohomology over the ground field. Special elements in Iwasawa 
 cohomology that arise from Euler systems become divisible by a certain Eul
 er factor upon norming down to the ground field. In certain instances\, th
 ere are reasons to wonder whether this divisibility can also hold for the 
 image in intermediate cohomology. Using “intermediate” Coleman maps\, 
 we shall see that the situation locally at $p$ is as nice as one could ima
 gine.\n\npre-talk at 1:20pm\n
