Exact propagating multi-anti-kink soliton solutions of a (3+1)-dimensional B-type Kadomtsev–Petviashvili equation

We explore the shape changing and cle- vaging nature of anti-kink solutions of a (3+1)-dimen- sional B-type Kadomtsev–Petviashvili equation. We achieved this by invoking the multiple exp-function method aided with symbolic computation which rem- ains an indispensable tool to deal with computational algebraic systems.
