Abstract: I discuss the notion of asymptotic safety and possible applications to quantum field theories of gravity and matter. What is asymptotic safety? We want to discuss the high energy behavior of a quantum field theory (QFT). Assume that a “theory space ” has been defined by giving a set of fields, their symmetries and a class of action functionals depending on fields φ and couplings gi. We will write gi = kdi g̃i, where k is a momentum cutoff and di is the mass dimension of gi. The real numbers g̃i are taken as coordinates in theory space. Ideally the couplings gi should be defined in terms of physical observables such as cross sections and decay rates. In any case “redundant ” couplings, i.e. couplings that can be eliminated by field redefinitions, should not be included. We also assume that a Renormalization Group (RG) flow has been defined on theory space; it describes the dependence of the action on an energy scale k (or perhaps a “RG time” t = log k). The action is assumed to have the form Γk(φ, gi) =∑ i gi(k)Oi(φ) , (1) where Oi are typically local operators constructed with the field φ and its derivatives, which are compatible with the symmetries of the theory. We identify theories with RG trajectories. It can generically be expected that when k goes to infinity some couplings gi(k) also go to infinity. What we want to avoid is that the dimensionless couplings g̃i diverge. In fact, there are famous examples such as QED and φ4 theory where this happens even at some finite scale kmax. Such

Abstract. We introduce a twospecies fractional reactiondiffusion system to model activatorinhibitor dynamics with anomalous diffusion such as occurs in spatially inhomogeneous media. Conditions are derived for Turing instability induced pattern formation in these fractional activatorinhibitor systems whereby the homogeneous steady state solution is stable in the absence of diffusion, but becomes unstable over a range of wavenumbers when fractional diffusion is present. The conditions are applied to a variant of the GiererMeinhardt reaction kinetics which has been generalized to incorporate anomalous diffusion in one or both of the activator and inhibitor variables. The anomalous diffusion extends the range of diffusion coefficients over which Turing patterns can occur. An intriguing possibility suggested by this analysis, which can arise when the diffusion of the activator is anomalous but the diffusion of the inhibitor is regular, is that Turing patterns can exist even when the diffusion coefficient of the activator exceeds that of the inhibitor.
