Abstract

We present a study of phi-four theory on noncommutative spaces using a combination of the Wilson renormalization group recursion formula and the solution to the zero dimensional vector/matrix models at large NN. Three fixed points are identified. The matrix model θ=\theta=\infty fixed point which describes the disordered-to-non-uniform-ordered transition. The Wilson-Fisher fixed point at θ=0\theta=0 which describes the disordered-to-uniform-ordered transition, and a noncommutative Wilson-Fisher fixed point at a maximum value of θ\theta which is associated with the transition between non-uniform-order and uniform-order phases.
