 via corrections to the Mullins-Sekerka motion.

ABSTRACT.  We develop an alternative method to matched asymptotic 
expansions for the construction of approximate solutions of the 
Cahn-Hilliard equation suitable for the study of its sharp interface 
limit. The method is based on the Hilbert expansion 
used in kinetic theory. Besides its relative simplicity, it leads to 
calculable higher order corrections to the interface motion.
