Renormalization Group

1995
The notion of renormalization group is not well defined. It arises in theories in which a prominent role is played by scale invariance or covariance properties, of various quantities, with respect to a noninvertible transformation of coordinates.

Operator renormalization group

Physical Review D, 1988
We introduce a novel operator renormalization-group method. This is a new and more powerful variant of the t expansion combining that method with the real-space renormalization-group approach. The aim is to extract infinite-volume physics at t..-->..infinity from calculations of only a few powers of t.

RENORMALIZATION GROUP AND WORMHOLES

International Journal of Modern Physics D, 1992
We incorporate the curved spacetime renormalization group into Coleman’s analysis of cosmological constant vanishing in the framework of wormholes. It is shown that for asymptotically free or finite GUT’s in curved space, Coleman’s mechanism can be realized.

On the renormalization group

Il Nuovo Cimento, 1965
The origin of the renormalization group is re-examined and various applications of the theory are discussed. The attention is focused on the limitations of these methods, and it is found that supplementary conditions are required besides the group equations in order to get unique results. These additional conditions on the solutions form the very basis
