Based on geometry picture of gravitational gauge theory, the cosmological constant is determined theoreti-cally. The cosmological constant is related to the ave
The B-spline basis set method is used to study the properties of helium confined endohedrally at thegeometrical centre of a fullerene. The boundary conditions o
The importance of cosmological constant for the cosmological models is given. The variations of the cosmological model for parameters λ and k were discussed re
