Conformally Flat Spherically Symmetric Cosmological Models-revisited

Conformally flat spherically symmetric cosmological models representing a charged perfect fluid as well as a bulk viscous fluid distribution have been obtained. The cosmological constant Λ is found positive and is a decreasing function of time which is consistent with the recent supernovae observations. The physical and geometrical properties of the models are discussed.

Note on (conformally) semi-symmetric spacetimes

We prove that conformally semi-symmetric spacetimes are actually semisymmetric. We also present a complete refined classification of the semi-symmetric spacetimes. PACS numbers: 04.20.Cv, 02.40.Ky, 04.20.Jb

Conformally Covariant Differential Operators: Symmetric Tensor Fields

We extend previous work on conformally covariant differential operators to consider the case of second order operators acting on symmetric traceless tensor fields. The corresponding flat space Green function is explicitly constructed and shown to be in accord with the requirements of conformal invariance. PACS: 03.70.+k; 11.10.Kk; 11.25.Hf; 11.30.Ly

Conformally Symmetric Circle Packings: A Generalization of Doyle's Spirals

0 Conformally symmetric circle packings . A generalization of Doyle spirals

Circle packings (and more generally patterns) as discrete analogs of conformal mappings is a fast developing field of research on the border of analysis and geometry. Recent progress was initiated by Thurston’s idea [T] about the approximation of the Riemann mapping by circle packings. The corresponding convergence was proven by Rodin and Sullivan [RS]; many additional connections with analytic...
