本文将的全真实的扩张上的Schzech Eisenstein上圈推广到虚二次域的有限扩张上.通过评价某些循环上的上循环,我们参数化了Colmez以前考虑过的Hecke L-函数的复值,给出了他关于L-函数特殊值的代数性结果的上同调解释.
We generalize Sczech's Eisenstein cocycle forover totally real extensions ofto finite extensions of imaginary quadratic fields. By evaluating the cocycle on certain cycles, we parametrize complex values of Hecke L-functions previously considered by Colmez, giving a cohomological interpretation of his algebraicity result on special values of the L-functions.
