Abstract

In this paper we are concerned with the following Kirchhoff type problem involving the 1-Laplace operator : \begin{equation*} \left\{\begin{array}{llc} u_{t}-m\left(\int_{\Omega}|Du|\right)\Delta_{1} u=0 & \text{in}\ & \Omega\times (0,+\infty) , \\ u=0 & \text{on} &\partial \Omega\times (0,+\infty),\\ u(x,0)=u_{0}(x) & \text{in} &\Omega , \end{array}\right. \end{equation*} where ΩRN\Omega\subset \mathbb{R}^{N} (N1N\geq 1) is a bounded smooth domain, m:R+R+m :\mathbb{R}_{+}\rightarrow \mathbb{R}_{+} is an increasing continuous function that satisfies some conditions which will be mentioned further down, and Δ1u=div(DuDu)\Delta_1 u=\text{div}\left(\frac{Du}{|Du|}\right) denotes the 1-Laplace operator. The main purpose of this work is to investigate from the initial data u0u_{0} and the nonlinear function mm the existence and asymptotic behavior of solutions near the extinction time.
