Optimal Hardy Inequalities for Random Walks on $Z^{2}$

Philipp Hake, Matthias Keller, Felix Pogorzelski

We prove an optimal Hardy inequality for every aperiodic, symmetric random walk in $Z^{2}$ with finite variance. In particular, we verify null-criticality, and thus, optimal…

Optimal Hardy Inequality for Fractional Laplacians on the Lattice

Philipp Hake, Matthias Keller, Felix Pogorzelski

We study the fractional Hardy inequality on the integer lattice. We prove null-criticality of the Hardy weight and hence optimality of the constant. More specifically, we present a…

An Improved Discrete $p$ -Hardy Inequality

Florian Fischer, Matthias Keller, Felix Pogorzelski

We improve the classical discrete Hardy inequality for $1 < p < \infty$ for functions on the natural numbers. For integer values of $p$ the Hardy weight is an absolutely monotonic…
