"Effect of ion and negative ion temperatures on KdV and mKdV solitons in a multicomponent plasma", Nonlinear Dynamics, Vol.111, No.9, pp.8659-8671.0924090Xhttps://hdl.handle.net/20.500.12416/6757The formation of ion-acoustic solitons (IASs) in an unmagnetized plasma with negative ions has been investigated through the KdV equation in both the situations Q′(=mj/mi=negativetopositiveionmassratio) less and greater than one and the mKdV equation only for Q′> 1. The existence of both KdV and mKdV solitons has been established for α(=iontoelectrontemperatureratio)>β(=negativeiontoelectrontemperatureratio) and α< β, which is the new outcome of the current investigation. Furthermore, the existence of both compressive and rarefactive solitons for Q′> 1 and Q′< 1 has been demonstrated.eninfo:eu-repo/semantics/closedAccessIon-AcousticSolitary WavesUnmagnetized PlasmaWarm PlasmaArticle11198659867110.1007/s11071-023-08262-8
