estimates for matrix Schrödinger equations
Ivan Naumkin, Ricardo Weder
This paper is devoted to the study of dispersive estimates for matrix Schrödinger equations on the half-line with general boundary condition, and on the line. We prove $L^{p}-L^{p^…

Inverse scattering on the half line for the matrix Schrödinger equation
Tuncay Aktosun, Ricardo Weder
The matrix Schrödinger equation is considered on the half line with the general selfadjoint boundary condition at the origin described by two boundary matrices satisfying certain a…

Time delay for the Dirac equation
Ivan Naumkin, Ricardo Weder
We consider time delay for the Dirac equation. A new method to calculate the asymptotics of the expectation values of the operator $\int\limits_{0} ^{\infty}e^{iH_{0}t}ζ\left( \fra…
