Two forms of (3+1)-dimensional B-type Kadomtsev-Petviashvili equation: multiple soliton solutions

Two extended forms of a (3+1)-dimensional generalized B-type Kadomtsev-Petviashvili (BKP) equation are examined. We use the simplified Hereman-Nuseir form to establish one and two soliton solutions for each extended equation. We develop specific constraints that guarantee the existence of multiple soliton solutions for each equation.
