Renormalization of multicritical scalar models in curved space

Abstract We consider the leading order perturbative renormalization of the multicritical $$\phi ^{2n}$$ ϕ2n models and some generalizations in curved space. We pay particular attention to the nonminimal interaction with the scalar curvature $$\frac{1}{2}\xi \phi ^2 R$$ 12ξϕ2R and discuss the emergen...
