Quasi-Exactly Solvable Schr\"odinger Operators in Three Dimensions


The main contribution of our paper is to give a partial classification of the quasi-exactly solvable Lie algebras of first order differential operators in three variables, and to show how this can be applied to the construction of new quasi-exactly solvable Schr\"odinger operators in three dimensions.Comment: Published in SIGMA (Symmetry, Integrability and Geometry: Methods and Applications) at
