On the asymptotic behaviour of the restricted Dirichlet Laplacian of real order $s > 0$ on stretching tubes

Roberta Musina, Giulio Romani

We study spectral and variational properties of the (possibly) fractional Dirichlet Laplacian $(- Δ_{n + k})^{s}$ , $s > 0$ , on bounded subsets of $\mathbb R^n\times\mathbb R^…

Hardy-Sobolev inequalities involving mixed radially and cylindrically symmetric weights

Gabriele Cora, Roberta Musina, Alexander I. Nazarov

We deal with weighted Hardy-Sobolev type inequalities for functions on $R^{d}$ , $d \geq 2$ . The weights involved are anisotropic, given by products of powers of the distance…

Hardy type inequalities with mixed cylindrical-spherical weights: the general case

Roberta Musina, Alexander I. Nazarov

We continue our investigation of Hardy-type inequalities involving combinations of cylindrical and spherical weights. Compared to [Cora-Musina-Nazarov, Ann. Sc. Norm. Sup., 2024],…
