Abstract We study the GIT quotient of the minimal Schubert variety in the Grassmannian admitting semistable points for the action of maximal torus T, with respect to the T-linearized line bundle and show that this is smooth when When n = 7 and r = 3 we study the GIT quotients of all Richardson varieties in the minimal Schubert variety. This builds on work by Kumar [21], Kannan and Sardar [18], Kannan and Pattanayak [17], and Kannan et al. [16]. It is known that the GIT quotient of is projectively normal. We give a different combinatorial proof.
