Abstract : We will study the GIT quotients of Richardson varieties in the
Grassmannian by a maximal torus. We give a necessary and sufficient
combinatorial condition for which the quotient variety is smooth. If time
permits we will discuss the projective normality of torus quotients of
Grassmannian of planes in the complex n space using standard monomial
theory. The later is based on a joint work with Kannan and Subrahmanyam.
