Two solitons oblique collision in anisotropic non-extensive dusty plasma

Using an extended Poincaré-Lighthill-Kue method, the oblique collision of two dust acoustic 
solitons (DASs) in a magnetized non-extensive plasma with the effect of dust pressure 
anisotropy is studied. The dust fluid is supposed to have an arbitrary charge. A couple of 
Korteweg-de Vries (KdV) equations are derived for the colliding DASs. The phase shift of 
each soliton is obtained. It is found that the dust pressure anisotropy, the non-extensive 
parameter for electrons and ions, plays an important role in determining the collision ...
