Equivariant Riemann-Roch theorems for curves over perfect fields
Helena B. Fischbacher-Weitz, Bernhard Köck
We prove an equivariant Riemann-Roch formula for divisors on algebraic curves over perfect fields. By reduction to the known case of curves over algebraically closed fields, we fir…

Symmetric powers of Galois modules on Dedekind schemes
Bernhard Koeck
We prove a certain Riemann-Roch type formula for symmetric powers of Galois modules on Dedekind schemes which, in the number field or function field case, specializes to a formula…
