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

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