Local boundedness of weak solutions to elliptic equations with \(p, q\)-growth. (English) Zbl 1539.35091
Summary: This article is dedicated to Giuseppe Mingione for his \(50^{th}\) birthday, a leading expert in the regularity theory and in particular in the subject of this manuscript. In this paper we give conditions for the local boundedness of weak solutions to a class of nonlinear elliptic partial differential equations in divergence form of the type considered below in (1.1), under \(p, q\)-growth assumptions. The novelties with respect to the mathematical literature on this topic are the general growth conditions and the explicit dependence of the differential equation on \(u \), other than on its gradient \(Du\) and on the \(x\) variable.
