Instabilities in certain one-dimensional singular interfacial equation
Résumé
We re-examine a generalized singular equation to discuss the coarsening of growing interfaces, in the presence of Ehrlich-Schwoebel-Villain barrier that induces a pyramidal or mound-type structure without slope selection. Our aim is to obtain analytically results on the coarsening process by inspecting the behavior of branch of the steady state periodic solutions.
