摘要
Using the standard truncated Painleve analysis,we have obtained some new special types of soliton solutions of a(2-pl)-dimensional integrable model,the Nizhnik-Novikov-Vesselov equation.Starting from the standard truncation approach in the Painleve analysis,one can obtain a Backlund transformation to find a new solution from a known one.Usually,one can obtain only a single solitary wave solution from the Backlund transformation related to the truncated Painleve analysis starting from the trivial vacuum solution.In this paper,we find some special types of the multisoliton solutions from the truncated Painleve analysis and the trivial vacuum solution.
