A two loop test of Matrix Big Bang Model

Abstract

In this thesis we expand the effective action for the Matrix Big Bang presented in [9, 10] and indicate the interaction terms. Then we compute the two loop effective potential of this Matrix Big Bang model. We show that this two loop effective potentials are attractive near the big bang and turns off very rapidly in late time. The form of the potential indicates that they are coming from a multi-D-brane contribution establishing a connection between late time physics and cosmological singularity.
