An Einstein-Cartan ekpyrotic model with a steep-to-plateau scalar potential supports a torsion-driven nonsingular bounce in homogeneous contraction without chaotic behavior in the explored parameter space.
VI (late-time quintessence with V > 0) exists for λ 2 < 6 and has (x∗,y ∗,z ∗, Σ ∗, Ω k∗, Ω s∗ ) = ( λ√ 6, √ 1 − λ 2 6 , 0, 0, 0, 0 )
