### Abstract

The Minkowski space $\mathbb{R}_1^{n}$ is the vector space Rn with the pseudo-scalar productu.u=-u_1v_1+...+u_nv_n$, for any u=(u_1,...,u_n) and v =(v_1,..., v_n) inR_1^{n}. A non zero vector u em R^n_1 is spacelike if u.u>0$, lightlike ifu.u=0$ and timelike if u.u<0. These spaces are used in Physics, for example, in relativity theory R14 is a model for space and time. The induced metric …
