with Quasi-variational Structure

Abstract:
We consider a one-dimensional tumor invasion model of Chaplain--Anderson type with quasi-variational structure, which is originally proposed in \cite{Chaplain-Anderson-2003}. One object is to show the existence of global-in-time solutions by using the limit procedure for suitable approximate solutions. The other is to consider the asymptotic behaviors of global-in-time solutions as time goes to $\infty$. Actually, we construct at least one global-in-time solution, which enables us to consider the convergence to a certain constant steady-state solution as time goes to $\infty$ whenever the initial data satisfy suitable conditions.
Keywords: Asymptotic behavior, tumor invasion, quasi-variational inequality.
