Local Observables and Renormalization in Dirac–Segal Approach to QFT

Communications in Mathematics and Statistics. 2014. Vol. 2. No. 2. P. 155-161.

We explain the Dirac–Segal approach to quantum field theory. We study local observables in this approach and the theory of deformations. We found out that this theory of deformation in the second-order coincides with the renormalization of the same theory, would it be considered in Polyakov approach. We conjecture that it is still true to all orders.
