| contents | For $s_1,s_2\in(0,1)$ and $p,q \in (1, \infty)$, we study the following nonlinear Dirichlet eigenvalue problem with parameters $α, β\in \mathbb{R}$ driven by the sum of two nonlocal operators:
\begin{equation*}
(-Δ)^{s_1}_p u+(-Δ)^{s_2}_q u=α|u|^{p-2}u+β|u|^{q-2}u\;\;\text{in }Ω, \quad u=0\;\;\text{in } \mathbb{R}^d \setminus Ω, \ \ \ \qquad \quad \mathrm{(P)}
\end{equation*} where $Ω\subset \mathbb{R}^d$ is a bounded open set. Depending on the values of $α,β$, we completely describe the existence and non-existence of positive solutions to (P). We construct a continuous threshold curve in the two-dimensional $(α, β)$-plane, which separates the regions of the existence and non-existence of positive solutions. In addition, we prove that the first Dirichlet eigenfunctions of the fractional $p$-Laplace and fractional $q$-Laplace operators are linearly independent, which plays an essential role in the formation of the curve. Furthermore, we establish that every nonnegative solution of (P) is globally bounded. |
