RESUMEN
We have made a Painleve for
some coupled KdV systems, other than that of Hirota and Satsuma. These
equations are interesting from many aspects. Due to the coupling with the other
non-linear equation sometimes the singularity on the solution manifold becomes
logarithmic. Also it is seen that the position on the resonances depends upon
coupling parameters. We have analyzed in detail the structure of resonances and
the formation of the coefficients at the resonances positions following the
methodology of Ablowitz et al.
