ABSTRACT.
The paper focuses on a nonstandard Dirichlet problem driven by the operator $-Delta_p +muDelta_q$, which is a competing $(p,q)$-Laplacian with lack of ellipticity if $mu>0$, and exhibiting a reaction term in the form of a convection (i.e., it depends on the solution and its gradient) composed with the convolution of the solution with an integrable function. We prove the existence of a generalized solution through a combination of fixed-point approach and approximation. In the case $muleq 0$, we obtain the existence of a weak solution to the respective elliptic problem.
