Smoothing on $L^{1}$ for ground state transformed semigroups in non-local settings

Miłosz Baraniewicz, Kamil Kaleta

We study the $L^{1}$ -smoothing properties for a broad class of semigroups arising from the ground state transformation of Schrödinger semigroups with confining potentials associated…

Integral kernels of Schrödinger semigroups with nonnegative locally bounded potentials

Miłosz Baraniewicz, Kamil Kaleta

We give the upper and the lower estimates of heat kernels for Schrödinger operators $H = - Δ + V$ , with nonnegative and locally bounded potentials $V$ in $R^{d}$ , $d \geq 1$ . We…
