Title:

The q-characters of representations of quantum affine algebras

Abstract:

The q-characters of a quantum affine algebra are combinatorial objects that describe the
structure of irreducible finite-dimensional representations of this algebra.  The
evaluation map allows to use the q-characters of quantum affine algebra of type A_n as a
combinatorial tool for description of the underlying Lie algebra sl_n or gl_n.  In the
talk we will illustrate this application on corresponding examples and compute
q-characters of certain class of modules of quantum affine algebra of gl_\infty.
