We examined the (3+1)-dimensional Kadomtsev–Petviashvili–Boussinesq (KP-B) equation, which arises not only in fluid dynamics, superfluids, physics, and plasma physics but also construction of connections between hydrodynamic optical model fields. Moreover, unlike Kadomtsev–Petviashvili equation (KPE), KP-B allows modeling waves traveling both directions does require zero-mass assumption, is nec...
