Cosmological Constant or Quintessence

[pi.rootpi]

Hi! I have more questions.

1st. Is there any diference between Cosmological Constant and quintessence?

2nd. If there is, which is?


I've only understood that cosmological constant is the energy of the vacuum but I don't know what quitessence is, so please, could somebody tell me if there is any diference?


Thanks!
