👉 Charles Math, also known as Charles Mathis or Charles Mathis-Rochereau, was a French mathematician who made significant contributions to the field of mathematics, particularly in the areas of differential equations and dynamical systems. His most notable work is the "Théorie des équations différentielles ordinaires," published in 1876, which introduced the concept of "characteristic equations" to classify the solutions of linear differential equations. This theory provided a systematic approach to solving such equations, distinguishing between exponential growth and decay, oscillatory solutions, and periodic solutions. Charles Math's work laid the foundation for modern analysis of differential equations and influenced subsequent developments in dynamical systems, including stability theory and bifurcation analysis. His innovative methods and insights have had a lasting impact on both theoretical and applied mathematics, making him a pivotal figure in the history of the discipline.
