A (2+1)-dimensional perturbed KdV equation, recently introduced by W.X.Ma and B.Fuchssteiner, is proven to pass the Painlevé test for integrability well, and its 4×4 Lax pair with two spectral parameters is found. The results show that the Painlevé classification of coupled KdV equations by A.Karasu should be revised. Recently, Ma and Fuchssteiner [1… CONTINUE READING
