摘　　要：The Jeans instabilities in an unmagnetized, collisionless, isotropic self-gravitating matter system are investigated in the context of K-deFormed Kaniadakis distribution based on kinetic theory. The result shows that both the growth rates and critical wave numbers of Jeans instability are lower in the l-deformed Kaniadakis distributed self-gravitating matter systems than the Maxwellian case. The standard Jeans instability For a Maxwellian case is recovered under the limitation k = O.The Jeans instabilities in an unmagnetized, collisionless, isotropic self-gravitating matter system are investigated in the context of K-deFormed Kaniadakis distribution based on kinetic theory.
