Abstract |
The aim of the talk will be to present a complete solution to the minisuperspace quantization program of a reduction of N=1, D=4 supergravity on a general Bianchi IX homogeneous cosmology. Our study provides strong indication of hidden Kac-Moody structures, sustaining the recent conjecture about the existence of dualities between gravity theories and infinite dimensional cosets built from Kac-Moody groups. It also shows that the quantized contribution of the terms quartic in the Fermions generically leads to an avoidance of the zero-volume cosmological singularity, i.e. to a cosmological bounce. |
