Abstract: The asymptotic approach is suggested for the description of interacting
surface and internal oceanic solitary waves.  This approach allows one to describe a
stationary moving wave patterns consisting of two plane solitary waves moving at an
angle to each other.  The results obtained within the approximate asymptotic theory is
validated by comparison with the exact two-soliton solution of the
Kadomtsev-Petviashvili equation.  The suggested approach is equally applicable to a
wide class of non-integrable equations too.  As an example, the asymptotic theory is
applied to the description of wave patterns in the 2D Benjamin-Ono equation describing
internal waves in the infinitely deep ocean containing a relatively thin one of the

Biography: Yury Stepanyants graduated in 1973 with the HD of MSc Diploma from the Gorky
State University (Russia) and started to work as the Engineer with the Research
Radiophysical Institute in Gorky.  He proceeded his career with the Institute of Applied
Physics of the Russian Academy of Sciences (Nizhny Novgorod) from 1977 to 1997.  In 1983
Yury obtained a PhD in Physical Oceanography, and in 1992 he obtained a degree of Doctor
of Sciences in Geophysics.  After immigration in Australia in 1998, Yury worked for 12
years as the Senior Research Scientist with the Australian Nuclear Science and
Technology Organisation in Sydney.  Since July 2009 he holds a position of Full
Professor at the University of Southern Queensland in Toowoomba, Australia.  Yury has
published more than 100 journal papers, 3 books, several review papers and has obtained
3 patents.
