A bibliometric study of the entire corpus of quantum-physics articles published in Revista Mexicana de Física and indexed in well known scholarly databases is performed in three complementary stages: A descriptive performance of indicators, a keyword analysis and word-cloud visualization and a network analysis and science mapping. Such an approach allow the identification of periods of more prolific production as well as of leaders on this field within Mexico. Our findings document the quantitative and structural history of worldwide quantum-physics contributions to this journal

Este artículo presenta un análisis comparativo de métodos analíticos para resolver ecuaciones diferenciales ordinarias lineales de segundo orden con coeficientes constantes, con énfasis particular en el método de factorización de operadores diferenciales. Se examinan técnicas convencionales como la ecuación característica, coeficientes indeterminados, variación de parámetros y transformadas integrales, contrastándolas sistemáticamente con el enfoque de factorización. Este último descompone el operador diferencial de segundo orden en el producto de dos operadores de primer orden, transformando el problema original en una secuencia de subproblemas más simples. Mediante un ejemplo detallado de un oscilador amortiguado con fuerza externa exponencial decreciente, se demuestra que el método de factorización ofrece ventajas pedagógicas significativas, estableciendo que es una herramienta valiosa en contextos educativos.
This article presents a comparative analysis of analytical methods for solving second-order linear ordinary differential equations with constant coefficients, with particular emphasis on the differential operator factorization method. Conventional techniques such as the characteristic equation, undetermined coefficients, variation of parameters, and integral transforms are examined and systematically contrasted with the factorization approach. The latter decomposes the second-order differential operator into the product of two first-order operators, transforming the original problem into a sequence of simpler subproblems. Through a detailed example of a damped oscillator with a decreasing exponential external force, it is demonstrated that the factorization method offers significant pedagogical advantages, establishing it as a valuable tool in educational contexts.
