The essential spectrum of canonical systems

Christian Remling, Kyle Scarbrough

We study the minimum of the essential spectrum of canonical systems . Our results can be described as a generalized and more quantitative version of the characterization…

Oscillation theory and semibounded canonical systems

Christian Remling, Kyle Scarbrough

Oscillation theory locates the spectrum of a differential equation by counting the zeros of its solutions. We present a version of this theory for canonical systems and…

Toda maps, cocycles, and canonical systems

Christian Remling

I present a discussion of the hierarchy of Toda flows that gives center stage to the associated cocycles and the maps they induce on the functions. In the second part, these id…

Generalized Toda flows

Darren C. Ong, Christian Remling

The classical hierarchy of Toda flows can be thought of as an action of the (abelian) group of polynomials on Jacobi matrices. We present a generalization of this to the larger gro…

The inverse scattering transform for the KdV equation with step-like singular Miura initial profiles

Sergei Grudsky, Christian Remling, Alexei Rybkin

We develop the inverse scattering transform for the KdV equation with real singular initial data of the form , where and $r=…

Generalized reflection coefficients

Christian Remling

I consider general reflection coefficients for arbitrary one-dimensional whole line differential or difference operators of order . These reflection coefficients are semicontinu…
