Continuum limit of field theories regularized on a random lattice
  The continuum limit and scaling properties of an asymptotically free field theory regularized on a random lattice are compared with those on a regular square lattice. We work on random lattices parametrized by a degree of ``randomness'' $\kappa$. We show that the continuum limit exists and different $\kappa$ are related by a finite renormalization.
