Ergodic theory

7 lives in this collection worked in ergodic theory, from 1880 to today. Each has a full course on their life and the mathematics and physics they made.

Often together with: mathematical physics, functional analysis, homogeneous dynamics, lie groups, probability theory, set theory. All fields

  • Frigyes Riesz1880–1956

    Hungarian analyst, a founder of functional analysis, known for the Riesz–Fischer and Riesz representation theorems, the L^p spaces, the theory of compact operators and subharmonic functions.

    functional analysis, operator theory, real analysis

  • John von Neumann1903–1957

    Mathematician who founded the Hilbert-space formulation of quantum mechanics, operator algebras and game theory, and defined the stored-program computer.

    set theory, mathematical physics, functional analysis

  • Stanislaw Ulam1909–1984

    Polish-American mathematician of the Lwów school who introduced measurable cardinals, conjectured the Borsuk–Ulam theorem, invented the Monte Carlo method, co-designed the hydrogen bomb and ran the Fermi–Pasta–Ulam–Tsingou experiment.

    set theory, measure theory, topology

  • Yakov Sinai1935–

    Founder of the modern theory of chaotic dynamical systems through Kolmogorov–Sinai entropy, dispersing billiards, Markov partitions and SRB measures, and a leader of rigorous statistical physics.

    ergodic theory, dynamical systems, mathematical physics

  • Marina Ratner1938–2017

    Ergodic theorist who proved the rigidity of horocycle flows and Raghunathan's conjectures on unipotent flows, the foundation of homogeneous dynamics.

    ergodic theory, homogeneous dynamics, lie groups

  • Grigory Margulis1946–

    Proved superrigidity and arithmeticity of higher-rank lattices, built the first explicit expanders, and solved the Oppenheim conjecture by founding homogeneous dynamics.

    lie groups, ergodic theory, homogeneous dynamics

  • Maryam Mirzakhani1977–2017

    First woman to win the Fields Medal, for her work on the geometry and dynamics of Riemann surfaces and their moduli spaces.

    hyperbolic geometry, teichmüller theory, ergodic theory
