Can someone remind me what the difference between the Cosmological Constant ([itex]\Lambda[/itex]) and Dark Energy (DE)? Doesn't DE (with w = -1) show up in the Einstein's field equations in exactly the same way as [itex]\Lambda[/itex] does?(adsbygoogle = window.adsbygoogle || []).push({});

(In case your an expert, I was trying to understand the conclusion of http://arxiv.org/PS_cache/arxiv/pdf/0909/0909.3853v1.pdf" [Broken] paper)
