History of Macdonald–Kostka polynomials $\tilde K_{\lambda\mu}(q,t)$

 Title: Macdonald–Kostka polynomials $\tilde K_{\lambda\mu}(q,t)$ Definition: The Macdonald-Kostka polynomial $\tilde K_{\lambda\mu}(q,t)$ is the coefficient-  of HREF{Schur_polynomials}[the Schur polynomial] $s_\lambda$ in the expansion $\tilde-  H_\mu(x;q,t)=\sum_\lambda \tilde K_{\lambda\mu}(q,t)s_\lambda$ of the modified Macdonald-  polynomial $\tilde H_\mu$ CITE{HHL}.+  of the Schur polynomial $s_\lambda$ in the expansion $\tilde H_\mu(x;q,t)=\sum_\lambda+  \tilde K_{\lambda\mu}(q,t)s_\lambda$ of the modified Macdonald polynomial $\tilde+  H_\mu$ CITE{HHL}.
