Generalized lubrification models blow-up and global existence result.

J. Emile Rakotoson, J. Michel Rakotoson, Cédric Verbeke (2005)

RACSAM

We study a general mathematical model linked with various physical models. Especially, we focus on those models established by King or Spencer-Davis-Voorhees related to thin films extending the lubrication model studied by Bernis-Friedman. According to the initial data, we prove that, either, blow up or global existence can be obtained.

Global Attractor for a Fourth-Order Parabolic Equation Modeling Epitaxial Thin Film Growth

Ning Duan, Xiaopeng Zhao (2012)

Bulletin of the Polish Academy of Sciences. Mathematics

This paper is concerned with a fourth-order parabolic equation which models epitaxial growth of nanoscale thin films. Based on the regularity estimates for semigroups and the classical existence theorem of global attractors, we prove that the fourth order parabolic equation possesses a global attractor in a subspace of H², which attracts all the bounded sets of H² in the H²-norm.
