There is an interesting $q$-analogue of the character of a finite-dimensional module that involves the notion of $q$-multiplicity of weight due to Lusztig, and it specializes into a natural $q$-analogue of the Weyl dimension formula. 2. Yet another proof of the Weyl character formula follows from Kostant's version of Borel-Weil-Bott theorem involving Lie algebra cohomology (this can also be used to derive the BGG resolution). | |
