  • Speaker Corina Calinescu, Ohio State University
    • Title Intertwining vertex operators and combinatorial representation theory
    • Time/place Friday, 9/22/2006 1:00 pm in Hill 705
    • Abstract In this talk we discuss vertex-algebraic structure of certain substructures, called principal subspaces, of standard modules for affine Lie algebras. We give suitable presentations of these subspaces and we derive Rogers-Ramanujan-type recursions satisfied by the graded dimensions of the principal subspaces. Part of the talk is based on joint work with Jim Lepowsky and Antun Milas. This talk will be introductory.

  • Speaker Haisheng Li, Rutgers University-Camden
    • Title Certain generalizations of twisted affine Lie algebras and vertex algebras
    • Time/place Friday, 12/8/2006 1:00 pm in Hill 705
    • Abstract We shall talk on certain generalizations of twisted affine Lie algebras and a natural connection of such Lie algebras with vertex algebras in terms of quasi modules.
