Noether symmetries of two-field cosmological models

Abstract

We summarize our work on "hidden" Noether symmetries of multifield cosmological models and the classification of those two-field cosmological models which admit such symmetries.

Infrared behavior in tame hyperbolizable two-field models

“…The uniformized form of a hyperbolizable model is a two-field generalized -attractor model in the sense of [10]. Some aspects of such models were investigated previously in [11][12][13][14][15][16][17] (see [18][19][20][21] for brief reviews).…”
