Relativistic stable operators with critical potentials

Tomasz Jakubowski, Kamil Kaleta, Karol Szczypkowski

We give local in time sharp two sided estimates of the heat kernel associated with the relativistic stable operator perturbed by a critical (Hardy) potential.

Bound states and heat kernels for fractional-type Schrödinger operators with singular potentials

Tomasz Jakubowski, Kamil Kaleta, Karol Szczypkowski

We consider non-local Schrödinger operators $H = - L - V$ in $L^{2} (R^{d})$ , $d \geq 1$ , where the kinetic terms $L$ are pseudo-differential operators which are perturbations of th…
