Bourgain-Brezis-Mironescu formula for Riesz Potentials

Claros, A.; Pérez, C. (2026-10-01)

We identify the Bourgain--Brezis--Mironescu pointwise limit of the nonlocal potential operator $(1-\alpha)\, I_\alpha(\mathcal D^\alpha f)$, $0<\alpha<1$, where $I_\alpha$ denotes the Riesz potential and $\mathcal D^\alpha$ ...

An optimal fractional Hardy inequality on the discrete half-line

Das, U.; de la Fuente-Fernández, R. (2026-02-01)

In the context of Hardy inequalities for the fractional Laplacian (-ΔN)σ on the discrete half-line N, we provide an optimal Hardy-weight Wσop for exponents σ∈0,1. As a consequence, we provide an estimate of the sharp constan...
