摘要

In this paper, we deal with a new kind of elliptic competing inclusions which involve variable exponent double-phase operators with logarithmic perturbation, nonlocal terms, mixed boundary conditions and multivalued convection terms. We here establish a new framework for determining the existence of generalized solutions and strongly generalized solutions to such type of problems. Our results extend the recent ones by Cen–Marano–Zeng (Appl Math Lett 167:109556, 2025).
