Markov theorem: In mathematics the Markov theorem gives necessary and sufficient conditions for two braids to have closures that are equivalent knots or links. The conditions are stated in terms of the group structures on braids.

Ergodic Theory: Ergodic Theory is the mathematical theory of well-behaved randomness. The random variables can occur discretely or continuously, but the total probability over the time period is always 1 so that the end of the time period, the random event ... [69%] 2023-02-22 [Mathematics]
Ergodic theory: metric theory of dynamical systems 1) In the "abstract" or "general" part of ergodic theory one examines measurable dynamical systems.
