Abstract:
We deal with the asymptotic behavior as $p\to 1^+$ of weak solutions to nonlinear Dirichlet problems modeled by \begin{equation*} \begin{cases} -\Delta_p u + |u|^{p-1}u = -\text{\text{div}}\left(|u|^{p-2}u E(x)\right) + |\nabla u|^{p-2}\nabla u\cdot F(x) + f(x) & \text{ in }\Omega, \ u=0 & \text{ on }\partial\Omega, \end{cases} \end{equation*} where $\Omega$ is an open bounded subset of $\mathbb{R}^N$ ($N\ge 2$). We focus on the a priori estimates depending on the norm of the Lebesgue functions $E,F$ and $f$ which guarantee the existence of a limit problem in the framework of functions of bounded variation. This is a joint work with Francescantonio Oliva.
