DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OLS/210/">Co
 hesive powers of Galois extensions</a>\nby Henry Klatt (George Washington 
 University) as part of Online logic seminar\n\nInteractive livestream: htt
 ps://zoom.us/j/122323340\n\nAbstract\nA cohesive product is a computabilit
 y theoretic analog to an ultraproduct\, in which the domain is restricted 
 to a collection of partial computable functions\, and the role of the ultr
 afilter is played by a cohesive set.  Unlike the ultraproduct\, the cohesi
 ve power is always countable\, but it only obeys a fragment of Łoś's the
 orem.  In this talk we discuss recent work with Rumen Dimitrov\, Valentina
  Harizanov\, and Keshav Srinivasan on the relationship between cohesive pr
 oducts of various fields and their Automorphism groups to the Galois group
 s of the base fields.\n
