0940-7677in Brazil. Its aim is to present an introduction to the "algebraic" method in the perturbative renormalization of relativistic quantum field theory. Although this approach goes back to the pioneering works of Symanzik in the early 1970s and was systematized by Becchi, Rouet and Stora as early as 19

The main tool being the renormalized version of the Schwinger action principle , the . (QAP), a section will be devoted to the latter.

Introduction,e underline, in particular, the well established and successful applications to the gauge theories of particle interactions: QED, the standard model, QCD and supersymmetric extensions thereof. Although a quantum theory of gravity has not yet been firmly formulated, there are now hopes for a consistent field theoretical description as well .

Yang-Mills Gauge Theories,e and demonstrated its role in guarantying the unitarity of the .-matrix and the gauge independence of the physical observables, on the one hand, and set up the general iterative construction needed in the absence of an invariant regularization. Precisely the latter approach is called “algebraic renormalization” in the present book.
