Asymptotics of the coupled solutions of the Kadomtsev-Petviashvili equation
Abstract:
We determine the set in R2 and the measure on this
set which allow to construct the coupled non-localized solutions of the
KP-I equation, which are connected by the change of variables x-->-x,
t--> -t, and split into the asymptotic solitons
as t--> \infty in the neighbourhood of the leading edge and back
front of the solution respectively. The solitons corresponding to each
of the solutions have the different amplitudes and lines of constant phase.
