We introduce and study natural generalisations of the Hermite and Laguerre polynomials in the ring of symmetric functions as eigenfunctions of infinite-dimensional analogues of partial differential operators of Calogero-Moser-Sutherland (CMS) type. In particular. we obtain generating functions. duality relations. https://www.spidertattooz.com/OMEGA-Seamaster-Aqua-Terra-150M-220-10-38-20-02-001-p15833/
