title = "Matrix model in - 2 dimensions and its effective field theory",

abstract = "We define a double scaling limit and operators in the d=-2 matrix model. Following Polchinski's argument in d=1, we explain the logarithmic scaling violations in d=-2 in terms of the tachyon effective action. We also show that KPZ scaling follows from Polchinski's argument in other dimensions.",
