We consider that the observable cosmological constant is the sum of the vacuum (Avac) and the induced term (Aind - 3m^2/4) with m being the ultra-llght masses (≈ Hubble parameter) implemented in the theory from...

Since the special relativity can be viewed as the physics in an inverse Wick rotation of four-dimensional (4D) Euclid space, which is at almost equal footing with the 4D Riemann/Lobachevski space, there should be im...
We combine the Freund-Rubin(FR)type anaatz with the nonlinear sigma model,a new solution of the chiral N=2,D=10 supergravity compactified on manifold M^(4)×N^(4)×H^(2) is obtained.Its properties are discussed.
