On equivariant Dedekind zeta-functions at $s=1$

Doc. Math. (Bielefeld) Extra Vol. Andrei A. Suslin's Sixtieth Birthday, 119-146 (2010)


We study a refinement of an explicit conjecture of Tate concerning the values at $s=1$ of Artin $L$-functions. We reinterpret this refinement in terms of Tamagawa number conjectures and then use this connection to obtain some important (and unconditional) evidence for our conjecture.
