DESCRIPTION:Title: Quivers\, Kac polynomials\, and zastava spaces.\n\nAbstr
 act: Quivers (aka directed graphs) have many interesting ties to combinato
 rics\, algebra\, and geometry. We'll begin this talk by overviewing the ba
 sics of quiver representations\, including Gabriel's Theorem\, leading tow
 ards a theorem of Kac which counts quiver representations in terms of Kac 
 polynomials. A remarkable theorem of Hua provides an explicit generating f
 unction for these Kac polynomials. We'll discuss how Hua's result can be i
 nterpreted in terms of certain interesting algebraic varieties called zast
 ava spaces\, via recent developments in mathematical physics (the theory o
 f Coulomb branches). This talk is based on joint work with Dinakar Muthiah
