Cohomological coprimality of Galois representations associated with modular forms
アブストラクト
Given two Galois representations, a natural question is to what extent they can be regarded as independent. Cohomological coprimality is a notion of independence that arises when each representation behaves as avanishing cohomology module with respect to the other's trivializing extension field. In this talk we share some of our observations on the cohomological coprimality for Galois representations associated with modular forms.
