Abstract

This paper is a continuation of our earlier paper [10]. With notations as in [10] (some of which are recalled in 1 and 2, below), we prove the following

1. THEOREM (6.1, below). The Picard group of a non-trivial Schubert variety Ω in the Grassmawt variety Gd,n is Z and is generated by the class of θΩ (1).
