Current observations with a decaying cosmological constant allow for chaotic cyclic cosmology
George F. R. Ellis, Emma Platts, David Sloan +1
We use the phase plane analysis technique of Madsen and Ellis to consider a universe with a true cosmological constant as well as a cosmological "constant" that is decaying. Time s…
