Advances in Mathematical Physics, Volume 2025, Issue 1, 2025.Lorentz transformations are central to relativistic mechanics, explaining phenomena such as the mass–energy relationship, spatial contraction, momentum transformation, velocity addition, and the geometric structure of Minkowski space‐time. While traditionally derived for motion along a single spatial axis, these transformations can be generalized to ...

Method of replacing the variables for generalized symmetry of the D'Alembert equation [PDF]
, 2002 We show that by the generalized understanding of symmetry, the D'Alembert equation for one component field is invariant with respect to arbitrary reversible coordinate ...

International Journal for Numerical Methods in Engineering, Volume 125, Issue 22, 30 November 2024.Abstract We introduce the fused sequential addition and migration (fSAM) algorithm for generating microstructures of fiber composites with long, flexible, nonoverlapping fibers and industrial volume fractions. The proposed algorithm is based on modeling the fibers as polygonal chains and enforcing, on the one hand, the nonoverlapping constraints by an ...

Comment D'Alembert a-t-il rencontré Grosley ?
, 2013 D'Alembert écrit à Grosley (GROSLEY , Pierre-Jean, né à Troyes le 18 novembre 1718 et mort à Troyes le 4 novembre 1785). On sait pas mal de choses sur Grosley (par exemple, la très bonne notice du Dict. journalistes), rédacteur des Ephémérides troyennes,

Functional Equations and Fourier Analysis
, 2013 By exploring the relations among functional equations, harmonic analysis and representation theory, we give a unified and very accessible approach to solve three important functional equations- the d'Alembert equation, the Wilson equation, and the d ...
