Geometry of conformal manifolds and the inversion formula

چکیده
Families of conformal field theories are naturally endowed with a Riemannian geometry which is locally encoded by correlation functions exactly marginal operators. We show that the curvature such manifolds can be computed using Euclidean and Lorentzian inversion formulae, combine operator content theory into an analytic function. Analogously, operators fixed dimension define bundles over manifold whose curvatures also formulae. These results relate to integrated four-point sensitive only behavior at separated points. apply these formulae derive convergent sum rules expressing in terms spectrum local their three-point function coefficients. further smoothly diverge if conserved current appears spectrum, or develops continuum. verify our explicitly $2d$ examples. In particular, for (2,2) superconformal we lower bound on scalar curvature, saturated free when central charge multiple three.

Conformal mappings preserving the Einstein tensor of Weyl manifolds
In this paper, we obtain a necessary and sufficient condition for a conformal mapping between two Weyl manifolds to preserve Einstein tensor. Then we prove that some basic curvature tensors of $W_n$ are preserved by such a conformal mapping if and only if the covector field of the mapping is locally a gradient. Also, we obtained the relation between the scalar curvatures of the Weyl manifolds r...
متن کاملOn the Conformal Geometry of Transverse Riemann-Lorentz Manifolds
Physical reasons suggested in [2] for the Quantum Gravity Problem lead us to study type-changing metrics on a manifold. The most interesting cases are Transverse Riemann-Lorentz Manifolds. Here we study the conformal geometry of such manifolds.
متن کاملConformal Geometry and 3-plane Fields on 6-manifolds
The purpose of this note is to provide yet another example of the link between certain conformal geometries and ordinary differential equations, along the lines of the examples discussed by Nurowski [3]. In this particular case, I consider the equivalence problem for 3-plane fields D ⊂ TM on a 6-manifold M satisfying the nondegeneracy condition that D + [D, D] = TM . I give a solution of the eq...
متن کاملThe inversion formula and holomorphic extension of the minimal representation of the conformal group
The minimal representation π of the indefinite orthogonal group O(m+ 1, 2) is realized on the Hilbert space of square integrable functions on R with respect to the measure |x|dx1 · · ·dxm. This article gives an explicit integral formula for the holomorphic extension of π to a holomorphic semigroup of O(m + 3,C) by means of the Bessel function. Taking its ‘boundary value’, we also find the integ...
متن کاملA Geometry Preserving Kernel over Riemannian Manifolds
Abstract- Kernel trick and projection to tangent spaces are two choices for linearizing the data points lying on Riemannian manifolds. These approaches are used to provide the prerequisites for applying standard machine learning methods on Riemannian manifolds. Classical kernels implicitly project data to high dimensional feature space without considering the intrinsic geometry of data points. ...
