A scalar Higgs field theory in de Sitter space-time has been investigated using the real time formulation of Semenoff and Weiss. We calculate the two-point function at late times and use it to obtain a general expression for the amplitude of fluctuation in energy density on scales which come out of
In three-dimensional de Sitter space S 3 1 and anti-de Sitter space H 3 1 , we generalize the classical BΓ€cklund theorem. Moreover, we obtain explicit forms of BΓ€cklund transformations (BTs) in the Tchebyshev coordinates and investigate the relation of loop group actions and BTs in S 3 1 .
