Central algebraic cohomology of Galois gerbes
Taeyeoup Kang
We study central algebraic cohomology of Galois gerbes over local fields of characteristic zero and number fields, with coefficients in a connected reductive group and an algebraic…

Abelian Galois cohomology of quasi-connected reductive groups
Mikhail Borovoi, Taeyeoup Kang
In 1999 Labesse introduced quasi-connected reductive groups and investigated their abelian Galois cohomology over local and global fields of characteristic 0. We (1) generalize som…
