**Aleksandr Lyapunov** was a school friend of Markov
and later a student of Chebyshev.
He did important work on differential equations, potential theory, stability
of systems and probability theory.

His work concentrated on the stability of equilibrium and motion of
a mechanical system and the stability of a uniformly rotating fluid. He
devised important methods of approximation. Lyapunov's methods, introduced
by him in 1899, provide ways of determining the stability of sets of ordinary
differential equations.
