**Asymptotic freedom** — In physics, asymptotic freedom is the property of some gauge theories in which the interaction between the particles, such as quarks, becomes arbitrarily weak at ever shorter distances, i.e. length scales that asymptotically converge to zero (or … Wikipedia

**Scattering length** — The scattering length in quantum mechanics describes low energy scattering. It is represented by the term a. General concept When a slow particle scatters off a short ranged scatterer (e.g. an impurity in a solid or a heavy particle) it cannot… … Wikipedia

**von Bertalanffy growth curve** — a model of individual fish growth as a function of time. Named after its proponent, Ludwig von Bertalanffy, this growth curve is an entry point to more complex models of the dynamics of fish populations. The growth equation is Lt = L∞1 e K(t to) … Dictionary of ichthyology

**Dehn function** — In the mathematical subject of geometric group theory, a Dehn function, named after Max Dehn, is an optimal function associated to a finite group presentation which bounds the area of a relation in that group (that is a freely reduced word in the … Wikipedia

**Systolic geometry** — In mathematics, systolic geometry is the study of systolic invariants of manifolds and polyhedra, as initially conceived by Charles Loewner, and developed by Mikhail Gromov and others, in its arithmetic, ergodic, and topological manifestations.… … Wikipedia

**Bernoulli number** — In mathematics, the Bernoulli numbers Bn are a sequence of rational numbers with deep connections to number theory. They are closely related to the values of the Riemann zeta function at negative integers. There are several conventions for… … Wikipedia

**Statistical inference** — In statistics, statistical inference is the process of drawing conclusions from data that are subject to random variation, for example, observational errors or sampling variation.[1] More substantially, the terms statistical inference,… … Wikipedia
