Singular-value decomposition of solution operators to model evolution equations
Alexandru Aleman, Joe Viola
We consider evolution equations generated by quadratic operators admitting a decomposition in creation-annihilation operators without usual ellipticity-type hypotheses; this class…

On weak and strong solution operators for evolution equations coming from quadratic operators
Alexandru Aleman, Joe Viola
We identify, through a change of variables, solution operators for evolution equations with generators given by certain simple first-order differential operators acting on Fock spa…

Pseudospectra in non-Hermitian quantum mechanics
D. Krejcirik, P. Siegl, M. Tater +1
We propose giving the mathematical concept of the pseudospectrum a central role in quantum mechanics with non-Hermitian operators. We relate pseudospectral properties to quasi-Herm…
