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

We prove that the submodule in K-theory which gives the exact value (up to 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 u...

Sumario:We prove that the submodule in K-theory which gives the exact value (up to 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 #Het2 (Ok [1/S], Vp(m)) in terms of the valuation of these p-adic L-functions, where Vp denotes the p-adic realization of a Hecke motive.
