De-Sitter nonlinear sigma model and accelerating universe
Joohan Lee, Tae Hoon Lee, Taeyoon Moon +1
We consider a cosmology with a non-compact nonlinear sigma model.The target space is of de-Sitter type and four scalar fields are introduced.The potential is absent but cosmologica…

Reply to "Comment on 'Scalar-tensor gravity coupled to a global monopole and flat rotation curves' "
Tae Hoon Lee, Byung Joo Lee
In Brans-Dicke theory of gravity we explain how the extra constant value in the formula for rotation velocities of stars in a galactic halo can be obtained due to the global monopo…

Cosmic String Spacetime in Dilaton Gravity and Flat Rotation Curves
Tae Hoon Lee
In dilaton gravity theories, we consider a string-like topological defect formed during U(1) gauge symmetry-breaking phase transition in the early Universe, and far from the cosmic…
