We establish a precise connection between two elliptic quasilinear problems with Dirichlet data in a bounded domain of R N . The first one, of the forminvolves a source gradient term with natural growth, where β is nonnegative, λ > 0, f (x) ≧ 0, and α is a nonnegative measure. The second one, of the formpresents a source term of order 0, where g is nondecreasing, and µ is a nonnegative measure. Here β and g can present an asymptote. The correlation gives new results of existence, nonexistence, regularity and multiplicity of the solutions for the two problems, without or with measures. New informations on the extremal solutions are given when g is superlinear.

“…the case of systems, was treated by DiBenedetto and Manfredi [18]. For similar results concerning equations with VMO-coefficients we refer to [31], [32] and the references therein. Finally, a complete Calderón-Zygmund theory for equations with non-standard p(x)-growth was achieved by Acerbi and Mingione [3].…”

The aim of this paper is to establish a Meyer's type higher integrability result for weak solutions of possibly degenerate parabolic systems of the typeThe vector-field a is assumed to fulfill a non-standard p(x, t)-growth condition. In particular it is shown that there exists ε > 0 depending only on the structural data such that there holds:loc , together with a local estimate for the p(·)(1 + ε)-energy.

“…There are numerous papers devoted to the L q bound (1.6) for solutions of (1.1) in the super-natural range q > p. The pioneer work [19] dealt with the case Ω = R n , and the paper [21] obtained a local interior bound. In [6], using a perturbation technique developed for fully nonlinear PDEs [5], the authors proved certain local W 1,q regularity for an associated homogeneous quasilinear equation.…”

Abstract. Lorentz and Lorentz-Morrey estimates are obtained for gradients of very weak solutions to quasilinear equations of the formwhere div A(x, ∇u) is modelled after the p-Laplacian, p > 1. The estimates are global over bounded domains that satisfy a mild exterior uniform thickness condition that involves the p-capacity. The vector field datum f is allowed to have low degrees of integrability and thus solutions may not have finite L p energy. A higher integrability result at the boundary of the ground domain is also obtained for infinite energy solutions to the associated homogeneous equations.
