We develop a formalism for performing real space renormalization group transformations of the " decimation type " using perturbation theory. The type of transformations beyond d = 1 is nontrivial even for free theories. We check the formalism on solvable case of O(N) symmetric Heisenberg chain. The transformation is particularly useful to study asymptotically free theories. Results for one clas...
