Abstract:
For a $p$-adic local field $K$ with perfect residue field, L. Herr constructed a complex which computes the Galois cohomology of a $p$-torsion representation of the absolute Galois group of $K$ by using the theory of $(\Phi,\Gamma)$-modules. We shall generalize his work to the imperfect residue field (the residue field has a finite $p$-basis) case.

Keywords: Galois cohomology, ($\Phi,\Gamma$)-modules.
