The manuscript is about the head-on collision of two dust-ion acoustic solitary waves (DIAS waves) in dusty plasma including inertial ions, negatively charged stationary dust particles and nonextensive electrons. For this purpose, using the extended Poincaré–Lighthill–Kuo (PLK) approach, two Kortwege–de Vries equations with solitonic solutions are derived and then phase shifts of DIAS waves after […]
