Abstract:

We study the existence of solutions to the equation $-\Delta_pu+g(x,u)=\mu$ when $g(x,.)$ is a nondecreasing function and $\mu$ a measure. We characterize the good measures, i.e. the ones for which the problem has a renormalized solution. We study particularly the cases where $g(x,u)= x ^{-\beta} u ^{q-1}u$ and $g(x,u)=\text{sign }(u)(e^{\tau u ^\lambda} -1)$. The results state that a measure is good if it is absolutely continuous with respect to an appropriate Lorentz-Bessel capacities.
