Generic simplicity for self-adjoint operators under bounded potential perturbations
Marianna Chatzakou, Bernard Helffer
We are interested in the generic simplicity of the spectrum of self-adjoint operators under bounded potential perturbations. More precisely, given a semibounded self-adjoint operat…

Fractional Schrödinger equations with singular potentials of higher order. II: Hypoelliptic case
M. Chatzakou, M. Ruzhansky, N. Tokmagambetov
In this paper we consider the space-fractional Schrödinger equation with a singular potential for a wide class of fractional hypoelliptic operators. Such analysis can be convenient…

Fractional Klein-Gordon equation with singular mass. II: Hypoelliptic case
M. Chatzakou, Michael Ruzhansky, Niyaz Tokmagambetov
In this paper we consider a fractional wave equation for hypoelliptic operators with a singular mass term depending on the spacial variable and prove that it has a very weak soluti…
