Critical discrete Hardy inequalities in $L^{p}$

Krzysztof Bogdan, Shubham Gupta, Kamil Kaleta +1

We establish ground-state representations and critical Hardy inequalities in the discrete $L^{p}$ setting. In particular, we construct critical Hardy weights for the discrete Dirichl…

IDS for subordinate Brownian motions in Poisson random environment on nested fractals

Hubert Balsam, Kamil Kaleta, Mariusz Olszewski +1

We establish the Lifshitz singularity of the integrated density of states (IDS) for random Schrödinger operators \[ H^ω = ϕ(-\mathcal{L}) + V^ω \] on planar unbounded nested fracta…

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…
