We investigate multiplicity and symmetry properties of higher eigenvalues and eigenfunctions of the p-Laplacian under homogeneous Dirichlet boundary conditions on certain symmetric domains Ω ⊂ R^N. By means of topological arguments, we show how symmetries of Ω help to construct subsets of W_0^(1,p)(Ω) with suitably high Krasnosel'ski˘ i genus. In particular, if Ω is a ball B ⊂ R^N , we obtain the following chain of inequalities: λ_2(p; B) ≤ · · · ≤ λ_(N+1)(p; B) ≤ λ_eq(p; B). Here λ_i(p; B) are…

In this work we analyze the behavior of the spectrum of the peridynamic fractional $p$-Laplacian, $(-\Delta_p)_{\delta}^s$, under the limit process $\delta\to0^+$ or $\delta\to+\infty$. We prove
