Long-time evolution of forced waves in the low viscosity regime

Nicolas Frantz, Michał Wrochna

We consider a model for internal waves described by a zero order pseudo-differential Hamiltonian $P$ damped by a second order viscosity term $i ν Q$ . Under Morse-Smale or similar we…

Dirac operators and local invariants on perturbations of Minkowski space

Nguyen Viet Dang, András Vasy, Michał Wrochna

For small perturbations of Minkowski space, we show that the square of the Lorentzian Dirac operator $P = - D^{2}$ has real spectrum apart from possible poles in a horizontal strip. Fu…
