Abstract: The existence of nonlinear superposition between lump, stripe soliton, Y-shaped soliton and breather waves of the (2+1)-dimensional combined pKP-BKP equation is explored. These nonlinear superpositions present interesting interaction red modes in nonlinear systems. The obtained special structures among lump waves, breather waves, stripe waves and Y-shaped soliton show rare attribute that the single lump does not interact with or always lies on the other localized waves. Furthermore, by using the nonlinear superposition equations and velocity resonance mechanisms, the molecular bound states among lump, stripe solitons, breather waves are formed. Such solutions provide brand new insights into the areas of plasma physics, hydrodynamics and nonlinear optics.
