Elliptic finite-band potentials of a non-self-adjoint Dirac operator
Gino Biondini, Xu-Dan Luo, Jeffrey Oregero +1
We present an explicit two-parameter family of finite-band Jacobi elliptic potentials for a non-self-adjoint Dirac operator which connects two previously known limiting cases in wh…

On the spectrum of the periodic focusing Zakharov-Shabat operator
Gino Biondini, Jeffrey Oregero, Alexander Tovbis
The spectrum of the focusing Zakharov-Shabat operator on the circle is studied, and its explicit dependence on the presence of a semiclassical parameter is also considered. Several…
