摘要：
By using the truncated Painleve expansion and consistent Riccati expansion (CRE), we investigate a dissipative (2 + 1)-dimensional Ablowitz-Kaup-Newell-Segur (AKNS) equation. Through the truncated Painleve expansion, its nonlocal symmetry and Backlund transformation (BT) are presented. Then the nonlocal symmetry is localized to the corresponding nonlocal group by an enlarged system. Based on the CRE method proposed by Lou (2013), the AKNS equation is proved CRE solvable, and the soliton-cnoidal wave interaction solutions are explicitly given. (C) 2017 Elsevier Ltd.
