,Maxwell’s Equations and Electromagnetic Waves over a Curved Space-Time,acobian, of the coordinates of the same point x in the second chart. The third and fourth derivatives of these functions exist, but are only piecewise continuous. We shall see that these hypothesis of differentiability are in strict relation with the field equations of general relativity and, as a consequence, with physics.Abjure 发表于 2025-3-27 14:06:20
