AN APPLICATION OF NEUTRIX CALCULUS TO QUANTUM FIELD THEORY
AN APPLICATION OF NEUTRIX CALCULUS TO QUANTUM FIELD THEORY
Neutrices are additive groups of negligible functions that do not contain any constants except 0. Their calculus was developed by van der Corput and Hadamard in connection with asymptotic series and divergent integrals. We apply neutrix calculus to quantum field theory, obtaining finite renormalizations in the loop calculations. For renormalizable …
