Rigid meromorphic cocycles for orthogonal groups

Abstract: I will talk about a generalization of Darmon and Vonk’s notion of rigid meromorphic cocycles to the setting of orthogonal groups. After giving an overview over the general setting I will discuss the case of orthogonal groups attached to quadratic spaces of signature (3,1) in more detail. This is joint work with Henri Darmon and Mike Lipnowski.
