"... By analyzing SU(3)×U(1) invariant stationary point, studied earlier by Nicolai and Warner, of gauged N = 8 supergravity, we find that the deformation of S 7 gives rise to nontrivial renormalization group flow in a threedimensional boundary super conformal field theory from N = 8, SO(8) invariant UV ..."

Singularities of renormalization group flows
 J. Geom. Phys
"... Abstract. We discuss singularity formation in certain renormalization group flows. A special case is the Ricci YangMills flow. We point out some results suggesting that topological hypotheses can make RG flows much less singular than Ricci flow. In particular we show that for rotationally symmetric ..."

Nonlinear Renormalization Group Flow and Optimization
"... Renormalization group flow equations for scalar λΦ 4 are generated using smooth smearing functions. Numerical results for the critical exponent ν in d = 3 are calculated by polynomial truncation of the blocked potential. It is shown that the convergence of ν with the order of truncation can be impro ..."

Renormalization Group Flow in CDT
"... We perform a first investigation of the coupling constant flow of the nonperturbative lattice model of fourdimensional quantum gravity given in terms of Causal Dynamical Triangulations (CDT). After explaining how standard concepts of lattice field theory can be adapted to the case of this backgro ..."

Selfconsistent renormalization group flow
"... A selfconsistent renormalization group flow equation for the scalar λφ 4 theory is analyzed and compared with the local potential approximation. The two prescriptions coincide in the sharp cutoff limit but differ with a smooth cutoff. The dependence of the critical exponent ν on the smoothness para ..."

On Renormalization Group Flow In Matrix Model
, 1992
"... The renormalization group flow recently found by Brézin and ZinnJustin by integrating out redundant entries of the (N+1)×(N+1) Hermitian random matrix is studied. By introducing explicitly the RG flow parameter, and adding suitable counter terms to the matrix potential of the one matrix model, we d ..."

Cosmological Models and Renormalization Group Flow
, 2002
"... Abstract: We study cosmological solutions of Einstein gravity with a positive cosmological constant and perfect fluid matter in diverse dimensions. These include bigbang models that recollaspse, bigbang models that approach de Sitter acceleration at late times, and bounce models that are both pas ..."

the interpretation of these cosmological solutions as renormalization group flows in a dual field theory and give a geometric interpretation of the associated cfunction as the area of the apparent cosmological horizon in Planck units. We find that the covariant entropy bound is violated in certain of our solutions
Renormalization Group Flow in large Nc
, 2008
"... We calculate renormalization group flow equations for the linear σmodel in large Nc approximation. The flow equations decouple and can be solved analytically. The solution is equal to a self consistent solution of the NJL model in the same approximation, which shows that flow equations are a promis ..."
