WebThe Commuting Variety 250 References 252 1. Introduction This article is an explication of some remarkable connections between the two-parameter symmetric polynomials discovered by Macdonald [1988] and the geometry of certain algebraic varieties, notably the Hilbert scheme Hilbn(C2)of points in the plane and the varietyC WebIn Section 5, we explore the extraneous boundary components of our commuting variety. These correspond to families of commuting birth-and-death processes having some zero transition probabilities which are not limits of commuting birth-and-death processes with positive transition probabilities.
