  • Algebraic structure of a class of differential equations including Heun is shown to be related with the deformations of sl(2) algebra. These include both quadratic and cubic ones. The finite dimensional representation of cubic algebra is explicitly shown to describe a quasi-exactly solvable system, not connected with sl(2) symmetry. Known finite dimensional representations of sl(2) emerge under special conditions. We answer affirmatively the question raised by Turbiner: Are there quasi- exactly… CONTINUE READING
