Kerr-Schild solutions in Multigravity and the Classical Double Copy
Hugo GarcÃa-Compeán, Everardo Rivera-Oliva
We explore the multimetric theory of gravitation, also known as multigravity. We derive additional new exact solutions for the theory in proportional Kerr-Schild and double Kerr-Sc…
Another formula for calculating Clebsch Gordan coefficients
Everardo Rivera-Oliva
This article presents the derivation of a comprehensive formula for the Clebsch-Gordan coefficients in a quantum system. The formula is derived by employing the iterative applicati…
Solving the Riccati Equation
Everardo Rivera-Oliva
In this study, the Riccati equation is resolved using the generalized recursive integrating factor method. By applying a non-linear transformation to the dependent variable …
Solving Linear Differential Equations by recursion and integrating factors
Everardo Rivera-Oliva
In this study, a recursive solution technique in conjunction with generalized integrating factors is presented and applied to address first and second order linear differential equ…
