A bstract We study correlation functions involving generalized ANEC operators of the form $$ \int {dx}^{-}{\left({x}^{-}\right)}^{n+2}{T}_{--}\left(\overrightarrow{x}\right) ? dx ? x n <mml:m...

We consider the multiple products of relevant and marginal scalar composite operators at Gaussian fixed-point in [Formula: see text] dimensions. This amounts to perturbative construction theory where parameters are momentum-dependent sources. Using exact renormalization group (ERG) formalism, we show how scaling properties sources given by short-distance singularities products.

In this paper, for any non-empty subset C of a pseudo BCI-algebra X, the concept of p-closure of C, denoted by C(pc), is introduced and some related properties are investigated. Applying this concept, a characterization of the minimal elements of X is given. It is proved that C(pc) is the least closed pseudo BCI-ideal of X containing C and K(X) for any ideal C of X...
