The Poincare Conjecture and the Cosmological Constant
Manifold Deformations the Poincare Conjecture the Cos-mological Constant

Abstract: The concept of deformation of Riemannian geometry is reviewed, with applications to gravitation and cosmology. Starting with an analysis of the cosmological constant problem, it is shown tha...
Towards a non-anthropic solution to the cosmological constant problem
non-anthropic solution cosmological constant problem
2010/12/21
Many probability measures in the multiverse depend exponentially on some observable parameters,
giving rise to potential problems such as youngness bias, Q-catastrophe etc. In this paper we explore a...
De Sitter brane-world, localization of gravity, and the cosmological constant
De Sitter brane-world localization of gravity cosmological constant

Cosmological models with a de Sitter 3-brane embedded in a five-dimensional de Sitter spacetime
(dS5) give rise to a finite 4D Planck mass similar to that in Randall-Sundrum (RS) brane-world
models ...
Cylindrically and toroidally symmetric solutions with a cosmological constant
toroidally symmetric solutions cosmological constant

Cylindrical-like coordinates for constant-curvature 3-spaces are introduced and discussed. This helps to clarify the geometrical properties, the coordinate ranges and the meaning of free parameters in...
