**Place:**27-325 (SNU) **Speaker**: Jaesung Kwon (UNIST)**Title**: Homological interpretation of Hecke $L$-values over real quadratic fields**Abstract**:

In this talk, I will demonstrate how to represent the Hecke $L$-values as the integral on the homology classes, which lives in the 2-dimensional complex manifolds with boundary. Also, I will construct a cyclotomic $p$-adic $L$-function, which interpolates the Hecke $L$-values, and give a criterion for the $\mu$-invariant of the $p$-adic $L$-function to be zero.
