http://personal.maths.surrey.ac.uk/st/jg0032/teaching/GLG1/notes/Glob.pdf WebA Lorentzian metric is a metric with signature (p, 1), or (1, p) . There is another notion of signature of a nondegenerate metric tensor given by a single number s defined as (v − p), where v and p are as above, which is equivalent to the above definition when the dimension n = v + p is given or implicit.

WebWe now begin the study of hyperbolic geometry. The first step is to define a new inner product on ℝ n, called the Lorentzian inner product. This leads to a new concept of length. In particular, imaginary lengths are possible. In Section 3.2, hyperbolic n -space is defined to be the positive half of the sphere of unit imaginary radius in ℝ n+1.
