Abstract. We generalise the Raychaudhuri equation for the evolution

of a self gravitating fluid to include an Abelian and non-Abelian

hybrid magneto fluid at a finite temperature. The aim is to utilise

this equation for investigating the dynamics of astrophysical high

temperature Abelian and non-Abelian plasmas.

Keywords. Raychaudhuri equation; plasmas; magneto fluids.
