Abstract

A depending on a complex parameter k superanalog SL of Calogero operator is costructed; it is related with the root system of the Lie superalgebra gl(n|m). For m = 0 we obtain the usual Calogero operator; for m = 1 we obtain, up to a change of indterminates and parameter k the operator constructed by Veselov, Chalykh and Fegin [2, 3]. For k = 1, 1 2 the operator SL is the radial part of the 2nd order Laplace oerator for the symmetric superspaces corresponding to pairs (GL(V )×GL(V ), GL(V )) and (GL(V ), OSp(V )), respectively. We will show that for the generic m and n the speranalogs of the Jack polynomials constructed by Kerov, Okunkov and Olshanskii [5] are eigenfunctions of SL; for k = 1, 1 2 they coinside with the spherical functions coresponding to the above mentioned symmetric superspaces. We also study the inner product induced by Berezin's integral on these superspaces.
