Talk Title |
Semiclassical behavior of the Mixmaster dynamics in the GUP framework |
Abstract |
The Mixmaster Universe is analyzed in a (string-inspired) generalized uncertainty principle framework. The model is studied in the ADM reduced phase space and the anisotropies satisfy a deformed Heisenberg algebra. Three main results are in order. (i) The deformation effects act as opposite of a stiff-matter. (ii) The triangular allowed domain is asymptotically stationary with respect to the point-Universe. (iii) No BKL map can be in general obtained since the Bianchi II model is no longer analytically integrable. |
