Milnor K 2 and p-adic zeta functions for real quadratic fields

G. Stevens ( http://math.bu.edu/people/ghs/research.html ) constructed a modular symbol taking values in circular K-groups, which is intimately related to Eisenstein series. We make precise a relationship between his Milnor K-theoretic modular symbol Φ M K and the period integrals of Eisenstein series. The main goal here is to extract from Φ M K a group 1-cocyle on SL 2 ( Q ) with values in differential form valued distributions and use this to construct a p-adic locally analytic distribution which gives a p-adic partial zeta function of a real quadratic field.
