We study a model of scalar quantum field theory in which space-time is adiscrete set of points obtained by repeatedly subdividing a triangle into threetriangles at the centroid. By integrating out the field variable at thecentroid we get a renormalized action on the original triangle. The exactrenormalization map between the angles of the triangles is obtained as well. Afixed point of this map happens to be the cotangent formula of Finite ElementMethod which approximates the Laplacian in two dimensions.
