Abstract
We introduce a novel operator renormalization-group method. This is a new and more powerful variant of the t expansion combining that method with the real-space renormalization-group approach. The aim is to extract infinite-volume physics at t..-->..infinity from calculations of only a few powers of t. Good results are obtained for the (1+1)-dimensional Ising model. The method readily generalizes to higher-dimensional spin theories and to a gauge-invariant treatment of gauge theories. These theories will require greater computational power.
