Conformal expansions and renormalons
The coefficients in perturbative expansions in gauge theories are factorially increasing, predominantly due to renormalons. This type of factorial increase is not expected in conformal theories. In QCD conformal relations between observables can be defined in the presence of a perturbative infrared fixed-point. Using the Banks-Zaks expansion we study the effect of the large-order behavior of th...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولOn Combinatorial Expansions of Conformal Blocks
In a recent paper [1] the representation of Nekrasov partition function in terms of nontrivial twodimensional conformal field theory has been suggested. For non-vanishing value of the deformation parameter ǫ = ǫ1 + ǫ2 the instanton partition function is identified with a conformal block of Liouville theory with the central charge c = 1 + 6ǫ2/ǫ1ǫ2. If reversed, this observation means that the un...
متن کاملConformal covariance of massless free nets
In the present paper we review in a fibre bundle context the covariant and massless canonical representations of the Poincaré group as well as certain unitary representations of the conformal group (in 4 dimensions). We give a simplified proof of the well–known fact that massless canonical representations with discrete helicity extend to unitary and irreducible representations of the conformal ...
متن کاملConformal positive mass theorems
We show the following two extensions of the standard positive mass theorem (one for either sign) : Let (N , g) and (N , g) be asymptotically flat Riemannian 3-manifolds with compact interior and finite mass, such that g and g are C and related via the conformal rescaling g = φg with a C− function φ > 0. Assume further that the corresponding Ricci scalars satisfy R ± φR ≥ 0. Then the correspondi...
