Asymptotic scalar field cosmology in string theory
Abstract Asymptotic (late-time) cosmology depends on the asymptotic (infinite-distance) limits of scalar field space in string theory. Such limits feature an exponentially decaying potential V ~ exp(−cϕ) with corresponding Hubble scale H ~ ϕ ̇ 2 + 2 V $$ \sqrt{{\dot{\phi}}^2+2V} $$ ~ exp(−λ Hϕ ), an...
