Abstract
  • In their 2004 paper, King, Tollu, and Toumazet consider the effects of stretching a Littlewood-Richardson coefficient by a positive integer N. When the L-R coefficient corresponding to N=1 is small (0,1,2, or 3), they conjecture simple polynomial formulas determining the L-R coefficient for all positive integers N. In this thesis, we consider generalizations of their conjecture to parabolic vector bundles and representations of quivers. In each instance, there is a polarized moduli space (M,L) with the property that the dimension of the global sections of the Nth tensor power of L scales in the same way as the corresponding generalized L-R coefficient. The "simple polynomial formulas" then translate to simple geometric descriptions of (M,L). We prove that these descriptions hold in many cases.
