Abstract
We obtain a resolution of the identity operator, for functions on a latticeɛZ d, which is derived from the block renormalization group. We use eigenfunctions of the terms of the decomposition to form a basis forl 2(ɛZd) and show how the basis is generated from lattice wavelets. The lattice spacingɛ is taken to zero and continuum wavelets are obtained.
