An extension theorem for conformal gauge singularities
نویسندگان
چکیده
We analyse conformal gauge, or isotropic, singularities in cosmological models in general relativity. Using the calculus of tractors, we find conditions in terms of tractor curvature for a local extension of the conformal structure through a cosmological singularity and prove a local extension theorem along a congruence of time-like conformal geodesics.

A global conformal extension theorem for perfect fluid Bianchi space-times
A global extension theorem is established for isotropic singularities in polytropic perfect fluid Bianchi space-times. When an extension is possible, the limiting behaviour of the physical space-time near the singularity is analysed.
متن کاملGauge Theories on Four Dimensional Riemannian Manifolds
This paper develops the Riemannian geometry of classical gauge theories Yang-Mills fields coupled with scalar and spinor fields on compact four-dimensional manifolds. Some important properties of these fields are derived from elliptic theory : regularity, an "energy gap theorem", the manifold structure of the configuration space, and a bound for the supremum of the field in terms of the energy....
متن کاملA Uniqueness Theorem of the Solution of an Inverse Spectral Problem
This paper is devoted to the proof of the unique solvability ofthe inverse problems for second-order differential operators withregular singularities. It is shown that the potential functioncan be determined from spectral data, also we prove a uniquenesstheorem in the inverse problem.

Perturbative d = 4, N = 1 heterotic vacua are characterized by a c = 9 conformal field theory (CFT) with (0, 2) worldsheet supersymmetry and the choice of a c̄ = 22 vector bundle. The space-time spectrum features the gravitational multiplet, non-Abelian vector multiplets, charged chiral matter multiplets Q , Q̂ and gauge neutral chiral moduli multiplets M . The couplings of these multiplets are d...

Singularities in the Yukawa and gauge couplings of N = 1 compactifications of the SO(32) heterotic string are discussed. Perturbative d = 4, N = 1 heterotic vacua are characterized by a c = 9 conformal field theory (CFT) with (0, 2) worldsheet supersymmetry and the choice of a ¯ c = 22 vector bundle. The space-time spectrum features the gravitational multiplet, non-Abelian vector multiplets, ch...
