FIZIKA A 9 (2000) 2 , 4754 ON SOME PROPERTIES OF (2 + 1)DIMENSIONAL PERTURBED KdV EQUATIONSWAPAN K. PAUL and A. ROY CHOWDHURY High Energy Physics Division, Department of Physics, Jadavpur
University, Received 2 December 1999; Accepted 6 July 2000Explicit solitarywave solutions of the (2 + 1)dimensional perturbed KdV equation
obtained by Ma et al. are obtained by using the Backlund transformation. Next, we obtain
the twosoliton solution in a form which implies a form of superposition. Lastly, the
corresponding modified equations are obtained by a new form of the Miura map. PACS numbers: 05.45.Yv
