Title: Positroid Links

Abstract: We will discuss how to obtain links from different combinatorial objects, namely bounded affine permutations, pairs of permutations (u,w) with u<= w where w is k-Grassmannian, and plabic graphs. We will also discuss how these links are related when the original objects correspond to each other under certain bijections. Our focus will be demonstrating these constructions and correspondences using examples.
