Abstract in different language:	We provide two existence results for sign-changing solutions to the Dirichlet problem for the family of equations $-\Delta_p u -\Delta_q u = \alpha |u|^{p-2}u + \beta |u|^{q-2}u$, where $1<q<p$ and $\alpha$, $\beta$ are parameters. First, we show the existence in the resonant case $\alpha\in\sigma(-\Delta_p)$ for sufficiently large $\beta$, thereby generalizing previously known results. The obtained solutions have negative energy. Second, we show the existence for any $\beta \geq \lambda_1(q)$ and sufficiently large $\alpha$ under an additional nonresonant assumption, where $\lambda_1(q)$ is the first eigenvalue of the $q$-Laplacian. The obtained solutions have positive energy.
