Title: Boundary Algebras of Positroids

Abstract: Positroid varieties are subvarieties of the Grassmannian defined by requiring the vanishing and nonvanishing of certain maximal minors. Positroid varieties are known to have a cluster structure which is categorified by the Gorenstein-projective module category over the completed boundary algebra of the associated dimer model. I will talk about positroid combinatorics and describe the boundary algebras which arise from arbitrary connected positroids.
