The derived Hecke algebra for dihedral weight one forms

Our goal is to understand the title giving preprint by Darmon, Harris, Rotger and Venkatesh (pdf), in which they verify some instances of a conjecture by and Harris–Venkatesh on the action of the derived Hecke algebra on modular forms of weight one.
