A positive cosmological constant as a geometrical artifact

In this paper, we revisit the classical mechanism to produce [Formula: see text]-dimensional spacetimes via Kaluza–Klein compactification. We made assumption that bulk geometry text] admits a Homothetic Vector Field (HVF) relaxing existence of zero i.e. holds on and homothetic bivector text]. Under these circumstances, identify origin positive cosmological constant in spacetime as factor representing geometrical artifact late time state spacetime.
