Multivariate Chebyshev polynomials in terms of singular elements
V. D. Lyakhovsky Saint Petersburg State University, St. Petersburg, Russia
Abstract:
We use the direct correspondence between Weyl anti-invariant functions and multivariate second-type Chebyshev polynomials to substantially simplify most operations with multivariate polynomials. We illustrate the obtained results by studying bivariate polynomials of the second type for root systems $A_1\oplus A_1$, $B_2$, and $G_2$.
Keywords:
generalized Chebyshev polynomial, semisimple Lie algebra, representation theory, Weyl group.
