Quasi exactly solvable operators and Lie superalgebras
Linear operators preserving the direct sum of polynomial rings P(m)⊕P(n) are constructed. In the case |m − n| = 1 they correspond to atypical representations of the superalgebra osp(2,2). For |m − n| = 2 the generic, finite dimensional representations of the superalgebra q(2) are recovered. Examples of Hamiltonians possessing such a hidden algebra are analyzed. PACS numbers: 02.20.Sv, 03.65.Fd ...
متن کاملReal Lie Algebras of Differential Operators and Quasi-Exactly Solvable Potentials
We first establish some general results connecting real and complex Lie algebras of first-order differential operators. These are applied to completely classify all finite-dimensional real Lie algebras of first-order differential operators in R. Furthermore, we find all algebras which are quasi-exactly solvable, along with the associated finitedimensional modules of analytic functions. The resu...
متن کاملQuasi - Exactly - Solvable Differential Equations
A general classification of linear differential and finite-difference operators possessing a finite-dimensional invariant subspace with a polynomial basis is given. The main result is that any operator with the above property must have a representation as a polynomial element of the universal enveloping algebra of the algebra of differential (difference) operators in finitedimensional represent...
متن کاملQuasi exactly solvable matrix Schrödinger operators
Two families of quasi exactly solvable 2 × 2 matrix Schrödinger operators are constructed. The first one is based on a polynomial matrix potential and depends on three parameters. The second is a one-parameter generalisation of the scalar Lamé equation. The relationship between these operators and QES Hamiltonians already considered in the literature is pointed out.
متن کاملThe hidden symmetry algebras of a class of quasi - exactly solvable multi dimensional operators
Let P (N, V) denote the vector space of polynomials of maximal degree less than or equal to N in V independent variables. This space is preserved by the enveloping algebra generated by a set of linear, differential operators representing the Lie algebra gl(V + 1). We establish the counterpart of this property for the vector space P (M, V) ⊕ P (N, V) for any values of the integers M, N, V. We sh...
