What's q? Did I miss something? --Paul 01:04, 10 November 2005 (UTC)

q is any positive integer, I guess. -lethe ^{talk +} 20:01, 27 February 2006 (UTC)

Concerning a merge with Metric signature, I'd like to comment that signature is a linear phenomenon. What makes most sense to me would be bilinear form explaining the signature phenomenon (linear case) and possibly linking to an article about Sylvester's rigidity theorem (dunno if this is the canonical name in english) -- this theorem is the basis for the whole thing. Metric signature should explain that at every point of the space, the metric tensor can be assigned a signature which is independent on the point. -- unreg 07:35, January 4 2006 (UTC)

In English it's called Sylvester's law of inertia. -lethe ^{talk +} 20:09, 27 February 2006 (UTC)
