报告摘要 Abstract:
Positroid varieties are open projective Richardson varieties in Grassmannian. Recently there has been a lot of studies on them from the point of view of cluster algebra, knot theory, representation theory and mathematical physics. Goodearl and Yakimov proved that positroid varieties are torus orbit of symplectic leaves with respect to the standard Poisson structure on grassmannian. In this talk we will give an algebraic geometric construction for positroid varities, which leads to a classification of symplectic leaves on them.
