The Bogolyubov-Parasyuk \(R\)-operation and operator expansions in massless theories
The paper is devoted to the applications of the Bernoulli-Parasiuk \(R\)- operation in the renormalization theory to the operator expansions for small distances and on the light cone. On this basis an extension of the Bogoliubov-Parasiuk \(R\)-operation is formulated for massless theories.
