DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FGC-IPM/21/"
 >Fine Selmer group of elliptic curves over global fields</a>\nby Somnath J
 ha (IIT Kanpur) as part of FGC-HRI-IPM Number Theory Webinars\n\n\nAbstrac
 t\nThe (p-infinity) fine Selmer group (also called the 0-Selmer group) of 
 an elliptic curve is a subgroup of the usual p-infinity Selmer group of an
  elliptic curve and is related to the first and the second Iwasawa cohomol
 ogy groups. Coates-Sujatha observed that the structure of the fine Selmer 
 group over the cyclotomic Z_p extension of a number field K is intricately
  related to Iwasawa's \\mu-invariant vanishing conjecture on the growth of
  p-part of the ideal class group of K in the cyclotomic tower. In this tal
 k\, we will discuss the structure and properties of the fine Selmer group 
 over certain p-adic Lie extensions of global fields. This talk is based on
  joint work with  Sohan Ghosh and Sudhanshu Shekhar.\n\nZoom link:\nhttps:
