Quasi-ergodicity of compact strong Feller semigroups on $L^{2}$

Kamil Kaleta, René L. Schilling

We study the quasi-ergodicity of compact strong Feller semigroups $U_{t}$ , $t > 0$ , on $L^{2} (M, μ)$ ; we assume that $M$ is a locally compact Polish space equipped with a locally finite…

Density of states for the Anderson model on nested fractals

Hubert Balsam, Kamil Kaleta, Mariusz Olszewski +1

We prove the existence and establish the Lifschitz singularity of the integrated density of states for certain random Hamiltonians $H^{ω} = H_{0} + V^{ω}$ on fractal spaces of infinite diame…

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…
