摘要：

We consider a parametric (p, q)-equations with sign-changing reaction and Robin boundary condition. We show that for all values of the parameter.bigger than a certain value which we determine precisely, the problem has at least three nontrivial solutions all with sign information and ordered. For the particular case of (p, 2)-equations we produce a second nodal solution, for a total of four nontrivial solutions. Under symmetry conditions, we show the existence of infinitely many nodal solutions. The same results are also valid for the Dirichlet problem. (c) 2021 The Author(s).
