Özet

Let G be the group M(n, 1) generated by all pseudo-orthogonal transformations and translations of Lorentzian space E-1(n) or G = SM(n, 1) is the subgroup of M(n, 1) generated by rotations and translations of E-1(n). We describe the correlations between Gram determinant detG(x(1),..., x(m)) of the system {x(1),..., x(m)} and the number of linearly independent null vectors in the system {x(1),..., x(m)}. Using methods of invariant theory and these results, the system of generators of the polynomial ring of all G-invariant polynomial functions of vectors x(1), x(2),..., x(m) in E-1(n) is obtained for groups G = M(n, 1) and G = SM(n, 1).
