Interaction of two soliton solution (2SS) of Generalised Kadomstev-Petviashvili (KP) equation in magnetised dust-ion-acoustic solitary waves (DIASWs) with Kappa electron velocity distribution

Using reduction perturbation technique (RPT) KP equation of magnetised DIASWs are reported in a complex plasma model. Also using Hirota’s Bilinear method (HBM) 2SS of KP equation is obtained. It has been observed that various physical parameters i.e. density ratio of ions to electrons (a)and spectral index (k) play significant role in the propagation and interaction of 2S. This study may be helpful to interpret the nonlinear characteristics of magnetised dusty plasma waves.
