Part of the Progress in Nonlinear Differential Equations and Their Applications book series (PNLDE, volume 4)


In General Relativity a gravitational field is described by a symmetric, second order tensor
$$ g \equiv g(z)\left[ {.,.} \right]z = ({z_0},...,{z_3})\varepsilon {^4} $$
on the space-time manifold R 4The tensor g is assumed to have the signature +, −, −, −; namely for all zR 4 the bilinear form g(z)[.,.] possesses one positive and three negative eigenvalues. The “pseudo-metric” induced by g is called Lorentz-metric.
