    "abstract": "Linear operators preserving the direct sum of polynomial rings P(m)\\oplus\nP(n) are constructed. In the case |m-n|=1 they correspond to atypical\nrepresentations of the superalgebra osp(2,2). For |m-n|=2 the generic, finite\ndimensional representations of the superalgebra q(2) are recovered. An example\nof a Hamiltonian possessing such a hidden algebra is analyzed.",
