Preface
Waves dynamics have fascinated us through out the history of civilization.

etc. have been studied for centuries. They have even inspired new fields of

hydrodynamic concepts/theories.

% f/ @5 v2 l1 SOur ability to quantitatively describe complex wave dynamics on thin films is
due to a fundamental physical fact - the waves are localized as solitary waves and
