Estimates for fully anisotropic elliptic equations with a zero order term.

Abstract Integral estimates for weak solutions to a class of Dirichlet problems for nonlinear, fully anisotropic, elliptic equations with a zero order term are obtained by symmetrization techniques. The anisotropy of the principal part of the operator is governed by a general n -dimensional Young function of the gradient which is not necessarily of polynomial type and need not satisfy the Δ 2 -condition.
