A relation between p-adic L-functions and the Tamagawa number conjecture for Hecke characters

摘要

We prove that the submodule in K-theory which gives the exact value $({text{up to }}mathbb{Z}_{(p)}^* )$ of the L-function by the Beilinson regulator map at non-critical values for Hecke characters of imaginary quadratic fields K with cl (K) = 1(p-local Tamagawa number conjecture) satisfies that the length of its coimage under the local Soulé regulator map is the p-adic valuation of certain special values of p-adic L-functions associated to the Hecke characters. This result yields immediately, up to Jannsen’s conjecture, an upper bound for $# H_{et}^2 (mathcal{O}_K [1/S],;V_p (m))$ in terms of the valuation of these p-adic L-functions, where V p denotes the p-adic realization of a Hecke motive.
