Quasi doubly-periodic solutions to a generalized Lame equation — •Michael Pawellek — Institut für Theoretische Physik III, Universität Erlangen-Nürnberg, Staudtstr.7, D-91058 Erlangen

We consider a generalization of the Lame equation, which can be written as a 1-d Schroedinger equation with quasi doubly-periodic potential depending on five parameters. We introduce a generalization of Jacobi’s elliptic functions and show that polynomial solutions in terms of these functions only for a finite set of values for these five parameters exist. For this purpose we also establish a relation to the generalized Ince equation.
