SINGLE AND MULTIPLE VALUED LOCALIZED EXCITATIONS OF BOITI-LEON-PEMPINELLI SYSTEM IN (2+1)-DIMENSIONS VIA A MAPPING METHOD.

With the help of a mapping approach, a new type of variable separation solution with two arbitrary functions to (2+1)-dimensional Boiti–Leon–Pempinelli system (BLP) is derived. Based on the derived variable separation solution, some single valued and multiple valued localized excitations such as dromions, peakons and foldons, etc. with novel evolutional properties are revealed by introducing appropriate initial conditions in this paper.
