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.countryscenesaddleryandpetsuppliers.shop/product-category/all-purpose-saddles/
