Operator renormalization group
Physical Review D, 1988We 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, 1992We 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.

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.

Quantum Gravity and the Functional Renormalization Group
, 2019During the past two decades the gravitational asymptotic safety scenario has undergone a major transition from an exotic possibility to a serious contender for a realistic theory of quantum gravity.

The renormalization group was originally introduced as a multiscale approach to quantum field theory and the theory of critical phenomena, explaining in particular the universality observed e.g. in critical exponents. Over the years it has become a powerful tool in the mathematical analysis of systems with infinitely many interacting degrees of freedom.
