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\n\nAbstract\nA cohesive prod
 uct is a computability theoretic analog to an ultraproduct\, in which the 
 domain is restricted to a collection of partial computable functions\, and
  the role of the ultrafilter is played by a cohesive set.  Unlike the ultr
 aproduct\, the cohesive power is always countable\, but it only obeys a fr
 agment of Łoś's theorem.  In this talk we discuss recent work with Rumen
  Dimitrov\, Valentina Harizanov\, and Keshav Srinivasan on the relationshi
 p between cohesive products of various fields and their Automorphism group
 s to the Galois groups of the base fields.\n
