Basic Vectors in Relativity

  • David A. de Wolf Virginia Tech (retired)


Basis vectors e(_alpha) play a useful role in special and general relativity. In particular they allow an expansion of the vectorial spacetime interval ds along infinitesimal curvilinear coordinate differences: ds = e(_alpha)(unit-xi), thus the conventional definition Usually a second coordinate system is needed to obtain explicit expressions for basis vectors. In this work, single-coordinate-system expressions for basis vectors [Eqs. (10) and (14)] are derived. Applications to nonorthogonal coordinate systems are worked out.
