Hamiltonian fluids in Bianchi universes

Résumé

By using the integrand factors method we put enlightening on two particular problems : a) to classify dissipative cosmological solutions which preserve the isotropy and the homogeneity; b) to explore easily the consequences of an stress-energy tensor possessing anisotropic pressure which depends non linearly on the expansion parameter, and to show that the associated shear pass through a maximum and vanishes assymptotically.
