We discuss the volume and surface running couplings for O(N) scalar theory in curved spacetime with boundaries. The IR limit of the theory in which it becomes asymptotically conformally invariant is studied, and the existence of IR fixed points for all couplings (also in D=4&= dimensions) is shown.
## Abstract We introduce a lattice model for a static and isotropic system of relativistic fermions. An action principle is formulated, which describes a particleβparticle interaction of all fermions. The model is designed specifically for a numerical analysis of the nonlinear interaction, which is
