Spectral Curves of Operators with Elliptic Coefficients
J. Chris Eilbeck, Victor Z. Enolski, Emma Previato
A computer-algebra aided method is carried out, for determining geometric objects associated to differential operators that satisfy the elliptic ansatz. This results in examples of…

PT Symmetry on the Lattice: The Quantum Group Invariant XXZ Spin-Chain
Christian Korff, Robert A. Weston
We investigate the PT-symmetry of the quantum group invariant XXZ chain. We show that the PT-operator commutes with the quantum group action and also discuss the transformation pro…

Complex WKB Analysis of a PT Symmetric Eigenvalue Problem
Mark Sorrell
The spectra of a particular class of PT symmetric eigenvalue problems has previously been studied, and found to have an extremely rich structure. In this paper we present an explan…
