| contents | In this article, we are concerned with the eigenvalue problem driven by the mixed local and nonlocal $p$-Laplacian operator having the interpolated Hardy term \begin{equation*} \mathcal{T}(u) :=- Δ_p u + (- Δ_p)^s u - μ\frac{|u|^{p-2}u}{|x|^{p θ}}, \end{equation*} where $0<s<1<p<N$, $θ\in [s,1]$, and $μ\in (0,μ_0(θ))$. First, we establish a mixed interpolated Hardy inequality and then show the existence of eigenvalues and their properties. We also investigate the Fuč\'ık spectrum, the existence of the first nontrivial curve in the Fuč\'ık spectrum, and prove some of its properties. Moreover, we study the shape optimization of the domain with respect to the first two eigenvalues, the regularity of the eigenfunctions, the Faber-Krahn inequality, and a variational characterization of the second eigenvalue. |
