Abstract

A method is sketched to make free quantum gravity finite and perhaps unitary when one regards it as the formal fourdimensional limit of the renormalizable one in 2+ɛ dimensions at sufficiently small ε The method utilizes the higherderivative regularization by a quadratic curvature term and is substantiated by some Symanzik’s conjectures on the nonrenormalizable theoriesIn questo lavoro si presenta un metodo originariamente sviluppato da Symanzik per le teorie di campo non rinormalizzabili per provare che la teoria quantistica di un campo gravitazionale puro è finita a tutti gli ordini perturbativi ed unitaria in 2+ɛdimensioni Allora si discute la teoria quantistica ottenuta nel limite formale ε→2 con particolare riguardo ai problemi di rinormalizzabilità
