Abstract:
The importance of the dispersive estimates for Schrödinger equations in spectral theory and in nonlinear analysis will be discussed. Furthermore, the literature on the $L^pL^{p'}$ estimates will be reviewed, starting with the early results in the 1990 th, and with an emphasis in the results in one dimension. New results will be presented, in $L^pL^{p'}$ estimates for matrix Schrödinger equations in the halfline, with general selfadjoint boundary condition, and in matrix Schrödinger equations in the fullline with point interactions. In both cases we consider integrable matrix potentials that have a finite first moment.
