Splet11. feb. 2024 · Constructing Minkowski cooordinates: Once the orthonormal tetrad of basis vectors or 1-forms has been carried unambiguously to the entire space, we can construct the four coordinate functions by doing path integrals such as $\Delta t=\int{d\mathbf{x}\cdot \mathbf{u}}$, where u is the 1-form that represents the gradient … SpletIt generalizes the notion of weak group inverse, which was introduced by Wang and Chen for complex matrices in 2024. Some new equivalent characterizations for elements to be weak group invertible are presented. Furthermore, we define the group-EP decomposition. Some properties of the weak group inverse are established by the group-EP decomposition.

SpletThe concept of range symmetric matrix is introduced in Minkowski space m. Equivalent conditions for a matrix to be range symmetric are determined. The existence of the Minkowski inverse of a range symmetric matrix in m is discussed. 1. Introduction We shall index the components of a complex vector in Cn from 0 to n−1, that is, u =(u0 ,u1,u2 ...
