Abstract

In this paper, we introduce a combinatorial path model of representation of the quantum affine algebra of type DnD_n, inspired by Mukhin and Young's combinatorial path models of representations of the quantum affine algebras of types AnA_n and BnB_n. In particular, we give a combinatorial formula for qq-characters of fundamental modules of type DnD_{n} by assigning each path to a monomial or binomial. By counting our paths, a new expression on dimensions of fundamental modules of type DnD_n is obtained.
