Modified Jeans instability and Friedmann equation from generalized Maxwellian distribution

We study Jeans instability with generalized Maxwellian distribution. The results reveal two significant features of the modified Jeans instability. First, the Jeans wavelength of the system covers the original λJ{\lambda }_{J} when k=1k=1. Second, as kk approaches 0, the modified Jeans wavelength ap...
