Perturbative Vacua from IIB Matrix Model

Understand

It has not been clarified whether a matrix model can describe various vacua of string theory.

• In this paper, we show that the IIB matrix model includes type IIA string theory.
• In the naive large N limit of the IIB matrix model, configurations consisting of simultaneously diagonalizable matrices form a moduli space, although the unique vacuum would be determined by complicated dynamics.
• This moduli space should correspond to a part of perturbatively stable vacua of string theory.
