On the focusing critical semi-linear wave equation
Joachim Krieger, Wilhelm Schlag
The focusing critical wave equation in three dimensions exhibits a special class of static solutions which are linearly unstable. These solutions decay like an inverse first power.…
Spectral Theory and Nonlinear PDE: a Survey
Wilhelm Schlag
This is a slightly modified version of the survey article. Minor changes to the text and the references have been made.
A remark on Littlewood-Paley theory for the distorted Fourier transform
Wilhelm Schlag
We show that the usual Mikhlin multiplier theorem relative to the distorted Fourier transform holds in the range (3/2,3) at least for radial functions and potentials. The restricte…
Non-generic blow-up solutions for the critical focusing NLS in 1-d
Joachim Krieger, Wilhelm Schlag
This paper addresses the existence of codimension one stable manifolds for the pseudo-conformal blow-up solution for critical one-dimensional NLS. By the work of Perelman and Merle…
Dispersive estimates for Schroedinger operators in the presence of a resonance and/or an eigenvalue at zero energy in dimension three: II
Mehmet Burak Erdogan, Wilhelm Schlag
We consider non-selfadjoint operators of the kind arising in linearized NLS and prove dispersive bounds for the time-evolution without assuming that the edges of the essential spec…
Dispersive estimates for Schroedinger operators: A survey
Wilhelm Schlag
We present some old and new results on dispersive estimates for Schroedinger equations.
