Supersymmetry and algebraic deformations
D. Gomez-Ullate, N. Kamran, R. Milson
We describe a class of algebraically solvable SUSY models by considering the deformation of invariant polynomial flags by means of the Darboux transformation. The algebraic deforma…

Quasi-Exact Solvability and the direct approach to invariant subspaces
D. Gomez-Ullate, N. Kamran, R. Milson
We propose a more direct approach to constructing differential operators that preserve polynomial subspaces than the one based on considering elements of the enveloping algebra of…
