Abstract

We establish integrality and congruence properties for the Eisenstein-Kronecker cocycle of Bergeron, Charollois and Garc\'ia introduced in [arXiv:2107.01992v2 [math.NT]]. As a consequence, we recover the integrality of the critical values of Hecke LL-functions over imaginary quadratic fields in the split case. Additionally, we construct a pp-adic measure that interpolates these critical values.
