**Small cancellation theory** — In the mathematical subject of group theory, small cancellation theory studies groups given by group presentations satisfying small cancellation conditions, that is where defining relations have small overlaps with each other. It turns out that… … Wikipedia

**Theil index** — The Theil index, [ [http://utip.gov.utexas.edu/papers/utip 14.pdf Introduction to the Theil index from the University of Texas] ] derived by econometrician Henri Theil, is a statistic used to measure economic inequality.MathematicsThe formula… … Wikipedia

**Quantum state** — In quantum physics, a quantum state is a mathematical object that fully describes a quantum system. One typically imagines some experimental apparatus and procedure which prepares this quantum state; the mathematical object then reflects the… … Wikipedia

**Kerr metric** — In general relativity, the Kerr metric (or Kerr vacuum) describes the geometry of spacetime around a rotating massive body. According to this metric, such rotating bodies should exhibit frame dragging, an unusual prediction of general relativity; … Wikipedia

**Income inequality metrics** — The concept of inequality is distinct from that of poverty[1] and fairness. Income inequality metrics or income distribution metrics are used by social scientists to measure the distribution of income, and economic inequality among the… … Wikipedia

**Generalized Kac–Moody algebra** — In mathematics, a generalized Kac–Moody algebra is a Lie algebra that is similar to a Kac–Moody algebra, except that it is allowed to have imaginary simple roots. Generalized Kac–Moody algebras are also sometimes called GKM… … Wikipedia

**Bounded deformation** — In mathematics, a function of bounded deformation is a function whose distributional derivatives are not quite well behaved enough to qualify as functions of bounded variation, although the symmetric part of the derivative matrix does meet that… … Wikipedia

**Dephasing rate SP formula** — The SP formula for the dephasing rate Γφ of a particle that moves in a fluctuating environment, unifies various results that have been obtained, notably in condensed matter physics with regard to the motion of electrons in a metal [1] [2] [3] [4] … Wikipedia
