What is Brane tension t3

  1. Jan 3, 2010 #1
    Can anyone help me with explaining what is Brane Tension (t_3)

    I'm reading an article on cosmology, and I need to understand it...

    Well, it's basically a tension (like a tension on a string) that wants to cause the brane to contract.

    I don't know if am I right; but my idea is that the Brane Tension is similar to a Cosmological constant on the Brane...

    Well, for that to be the case, it would need to be independent of scale. That is, if I stretched the brane (via cosmological expansion), the tension would remain the same. This may be the case, but I'm not so sure.
