Solitons for a (2+1)-dimensional Sawada Kotera equation via the Wronskian technique

Under investigation in this letter is a (2+1)-dimensional Sawada Kotera equation. Solitons are obtained by virtue of the Wronskian technique. Via the fourth-and sixth-order Plucker relations for the Wronskian, we give a proof for the N-soliton solutions. Interactions between/among the two/three solitons are investigated, and it seems that those interactions are elastic. (C) 2017 Elsevier Ltd. All rights reserved.
