General Covariance

Albert Einstein proposed this basic principle for his particular theory of relativity; even so, that theory was limited by space-time coordinate systems linked to the other person by uniform relative motions, the so-named “inertial frames.” In theoretical physics, general covariance may be the invariance of the sort of physical regulations under arbitrary differential coordinate transformations. A physical legislation expressed in a general covariant vogue requires the same mathematical web form coordinate systems and is normally expressed regarding tensor fields.
