Lyapunov type inequality for extremal Pucci's equations (1706.04329v1)

Abstract: In this article, we establish Lyapunov type inequality for the following extremal Pucci's equation \begin{equation*} \left{ \begin{aligned}{} \mathcal{M}^{+}_{\lambda,\Lambda}(D^{2}u)+a(x)u&=0~\text{in}~\Omega,\ u&=0~\text{on}~\partial\Omega, \end{aligned} \right. \end{equation*} where $\Omega$ is a smooth bounded domain in $\R^{N},~N\geq2$. This works generalize the well-known works on Lyapunov inequalities to fully nonlinear elliptic equations.
