DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/CMI/7
 /">$p$-adic Hodge theory and delta geometry</a>\nby Arnab Saha (Indian Ins
 titute of Technology (IIT) Gandhinagar) as part of CMI seminar series\n\n\
 nAbstract\nWe will talk about a new $p$-adic Galois representation that co
 mes from $\\delta$-geometry. Here\, we construct a new filtered Isocrystal
  associated to an abelian scheme that is different from the usual crystall
 ine cohomology. In the case of elliptic curves\, depending on a modular pa
 rameter\, this Isocrystal is also weakly admissible which leads to a new c
 rystalline Galois representation attached to the elliptic curve via the Fo
 ntaine functor. This is joint work with Jim Borger. \n\nWe will dedicate t
 he first half of the talk on giving an overview of $p$-adic Hodge theory a
 nd $\\delta$-geometry.\n
