  • In this paper we establish different ways to compute the period of a generic torsor of a group of multiplicative type. We also study the relationships among the periods of generic torsors of Q, T andW, where Q is a group of multiplicative type, T is the maximal subtorus of Q and W is the maximal finite quotient group of Q.
