Abstract

We study the existence of solutions to the equation \Gdpu+g(x,u)=μ-\Gd_pu+g(x,u)=\mu when g(x,.)g(x,.) is a nondecreasing function and \gm\gm a measure. We characterize the good measures, i.e. the ones for which the problem as a renormalized solution. We study particularly the cases where g(x,u)=\absxβ\absuq1ug(x,u)=\abs x^{\beta}\abs u^{q-1}u and g(x,u)=\absxτsgn(u)(eτ\absuλ1)g(x,u)=\abs x^{\tau}\rm{sgn}(u)(e^{\tau\abs u^\lambda}-1). The results state that a measure is good if it is absolutely continuous with respect to an appropriate Lorentz-Bessel capacities.
