  1. Isomorphism: In abstract algebra, an isomorphism (Greek: ison "equal", and morphe "shape") is a bijective map f such that both f and its inverse f are homomorphisms, i.e., structure-preserving mappings. In the more general setting of category theory, an ... [81%] 2023-06-01 [Functions and mappings] [Abstract algebra]...

  8. Ornstein isomorphism theorem: Ergodic theory, the study of measure-preserving transformations or flows, arose from the study of the long-term statistical behaviour of dynamical systems (cf. also Measure-preserving transformation; Flow (continuous-time dynamical system); Dynamical system).
