Spectral Analysis of Darboux Transformations for the Focusing NLS Hierarchy
Radu C. Cascaval, Fritz Gesztesy, Helge Holden +1
We study Darboux transformations associated with the focusing nonlinear Schrödinger equation (NLS_-) and their effect on spectral properties of the underlying Lax operator. The lat…
Real-Valued Algebro-Geometric Solutions of the Camassa--Holm hierarchy
Fritz Gesztesy, Helge Holden
We provide a treatment of real-valued, smooth, and bounded algebro-geometric solutions of the Camassa--Holm (CH) hierarchy and describe the associated isospectral torus. We also di…
Infinite dimensional representations of canonical algebras
Idun Reiten, Claus Michael Ringel
The aim of this paper is to extend the structure theory for infinitely generated modules over tame hereditary algebras to the more general case of modules over concealed canonical…
Generic differential equation for fractional flow of steady two-phase flow in porous media
Henning Arendt Knudsen, Alex Hansen
We report on generic relations between fractional flow and pressure in steady two-phase flow in porous media. The main result is a differential equation for fractional flow as a fu…
