Mesons in Gauge/Gravity Duals A Review
We review recent progress in studying mesons within gauge/gravity duality, in the context of adding flavour degrees of freedom to generalizations of the AdS/CFT correspondence. Our main focus is on the ‘top-down approach’ of considering models constructed within string theory. We explain the string-theoretical constructions in detail, aiming at non-specialists. These give rise to a new way of d...
متن کاملDuals and approximate duals of g-frames in Hilbert spaces
In this paper we get some results and applications for duals and approximate duals of g-frames in Hilbert spaces. In particular, we consider the stability of duals and approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of Hilbert spaces. We also obtain some results for perturbations of approximate duals.

متن کاملThe Duals of Warfield
A Warreld group is a direct summand of a simply presented abelian group. In this paper, we describe the Pon-trjagin dual groups of Warreld groups, both for the p-local and the general case. A variety of characterizations of these dual groups is obtained. In addition, numerical invariants are given that distinguish between two such groups which are not topologically isomorphic.

In [1] the light scalar meson nonet has been considered within the QCD sum rules approach with the interpolating current consisting of the scalar diquark and the scalar antidiquark. It has been shown that the negative contributions from the operators of dimension 8 are dominant in the sum rules, so that, there is no evidence of the coupling of the above tetraquark current with the light scalar ...
