Abstract:In this course we will present the vertex operator approach to symmetric functions. Symmetric functions figure prominently in representation theory and combinatorics. Roughly, we will talk about the following topics: 1) Preliminaries on symmetric functions 2) Schur functions and Bernstein vertex operators 3) Characters of S_n and the Murnaghan-Nakayama formula 4) Hall-Littlewood functions and their vertex operator realization 5) Plethystic operators and vertex operators 6) characters of Hecke algebras 7)Macdonald functions 8) Further applications: wreath products and other classical groups
