Abstract

Over a global field (number field or function field of a curve over a finite field), theorems for the Galois cohomology of algebraic groups have long been known. For FF the function field of a curve over the formal series field C((t))\mathbb{C}((t)), under an additional assumption on the curve, we establish an explicit description of the localization map in Galois cohomology. This is achieved by extending the theory of B(F,G)B(F,G) due to Kottwitz.
