Nonlinear equations with natural growth terms and measure data
Alessio Porretta Abstract:
We consider a class of nonlinear elliptic equations containing a -Laplacian type operator, lower order terms having natural growth with respect to the gradient, and bounded measures as data. The model example is the equation
in a bounded set , coupled with a Dirichlet boundary condition. We provide a review of the results recently obtained in the absorption case (when ) and prove a new existence result without any sign condition on , assuming only that . This latter assumption is proved to be optimal for existence of solutions for any measure .
