The Cauchy problem for a fourth-order thin film equation

Abstract

In this talk we will discuss different aspects of the Cauchy problem of a class of fourth order thin film equation of the form \(u_t = \Delta\cdot( (|u|^n\nabla\Delta u)\). We will show recent results in which we obtained a countable number of similarity solutions of the thin film equation via a homotopy transformation as \(n\to 0^+\) to the similarity solutions of the classic bi-harmonic equation \(u_t = \Delta^2 u\). Also, another similar homotopic approach is performed directly from the thin film equation to the parabolic bi-harmonic equation in order to obtain important properties for the Cauchy problem. This is joint work with Prof. Victor. A. Galaktionov at the University of Bath (UK).
