Abstract | In this paper, we generalize the one-parameter (c) family of inhomogeneous first-order differential operator representations of the orthogonal Lie algebras arising from conformal transformations to those of orthosymplectic Lie superalgebras, and determine the irreducible condition. Letting these supersymmetric differential operators act on the space of supersymmetric exponential-polynomial functions that depend on a parametric vector (a)over-right-arrow is an element of C-n, we prove that the space forms an irreducible osp(n + 2 vertical bar 2m)-module for any c is an element of C if (a)over-right-arrow is not on a certain hypersurface. By partially swapping differential operators and multiplication operators, we obtain more general supersymetric differential operator representations of osp(n + 2 vertical bar 2m) on the polynomial algebra l in n m supersymetric variables. Moreover, we prove that l forms an infinite-dimensional irreducible weight osp(n + 2 vertical bar 2m)-module with finite-dimensional weight subspaces if c is not an element of Z/2.
