Matrix Model Fixed Point of Noncommutative Phi-Four

In this article we exhibit explicitly the matrix model ($θ=\infty$) fixed point of phi-four theory on noncommutative spacetime with only two noncommuting directions using the Wilson renormalization group recursion formula and the 1/N expansion of the zero dimensional reduction and then calculate the mass critical exponent $ν$ and the anomalous dimension $η$ in various dimensions .
