P. Isaza et al., LOCAL SOLUTION FOR THE KADOMTSEV-PETVIASHVILI EQUATION IN R(2), Journal of mathematical analysis and applications, 196(2), 1995, pp. 566-587
In this paper we obtain results about local existence, uniqueness, reg
ularity, and continuous dependence on the initial data for the solutio
n of the Kadomtsev-Petviashvili equation with positive dispersion in R
(2)? and initial data in Sobolev spaces of order s greater than or equ
al to 3. Our method uses an approximated problem where the theory of q
uasi-linear evolution equations is applicable. (C) 1995 Academic Press
