Ergodic theory
Ergodic theory is the branch of dynamical systems theory that studies measure-preserving transformations, with roots in Boltzmann's ergodic hypothesis and applications to statistical mechanics, number theory, and combinatorics.
Ergodicity
Ergodicity is the property of a measure-preserving dynamical system where a single trajectory's time average equals its average over the whole space, central to ergodic theory.
Ergodicity and convergence to equilibrium of continuous-time Markov processes
Ergodicity and convergence to equilibrium of continuous-time Markov processes covers recurrence, stationary distributions, the ergodic theorem, and convergence rates from exponential spectral gaps to subgeometric ones.
Ergosphere
The ergosphere, also called the ergoregion, is the region just outside a rotating black hole's event horizon where everything is forced to rotate with the hole.
Ergothioneine
Ergothioneine (EGT) is a diet-derived antioxidant amino acid synthesized only by certain fungi and bacteria, obtained chiefly from mushrooms and studied as a possible micronutrient for healthy aging.
Ergotropy
Ergotropy is the maximum work extractable from a quantum system by cyclic unitary processes, introduced in 2004 and now the standard figure of merit for quantum batteries.
