Abstract

In this talk, I will begin by recalling the Macdonald pairings and Macdonald polynomials, which are symmetric functions that are pairwise orthogonal under this specific pairing.
Next, I will propose an interpretation of this pairing, based on the representations of the Lie algebra of currents.
Subsequently, I will elucidate the Gram-Schmidt algorithm within the corresponding derived category.
As a culmination of these discussions, I will unveil a collection of modules whose characters coincide with Macdonald polynomials, subject to specific substitutions.
