Aleksandr Lyapunov was a prominent Russian mathematician and theoretical physicist, best known for his work in the fields of stability theory, differential equations, and mathematical physics. Born on December 6, 1857, and passing away on November 3, 1918, he made significant contributions to various areas of mathematics. One of his most important contributions is the Lyapunov stability theory, which provides conditions under which the solutions of differential equations remain close to equilibrium points.
