# On Dark Energy, Weyl’s Geometry and Different Derivations of the Vacuum Energy Density

@article{Castro2007OnDE, title={On Dark Energy, Weyl’s Geometry and Different Derivations of the Vacuum Energy Density}, author={Carlos Castro}, journal={viXra}, year={2007} }

Two different derivations of the observed vacuum energy density are presented. One is based on a class of proper and novel generalizations of the (Anti) de Sitter solutions in terms of a family of radial functions R(r) that provides an explicit formula for the cosmological constant along with a natural explanation of the ultraviolet/ infrared ( UV/IR) entanglement required to solve this problem.....
