Discrete spectrum — For a mathematically rigorous point of view of discrete spectrum , see decomposition of spectrum (functional analysis). In physics, an elementary (and accurate) explanation of a discrete spectrum is that it is an emission spectrum or absorption… … Wikipedia
Continuous spectrum — The spectrum of a linear operator is commonly divided into three parts: point spectrum, continuous spectrum, and residual spectrum. If H is a topological vector space and is a linear map, the spectrum of A is the set of complex numbers λ such… … Wikipedia
Four-momentum — In special relativity, four momentum is the generalization of the classical three dimensional momentum to four dimensional spacetime. Momentum is a vector in three dimensions; similarly four momentum is a four vector in spacetime. The… … Wikipedia
Decomposition of spectrum (functional analysis) — In mathematics, especially functional analysis, the spectrum of an operator generalizes the notion of eigenvalues. Given an operator, it is sometimes useful to break up the spectrum into various parts. This article discusses a few examples of… … Wikipedia
Single particle spectrum — The single particle spectrum is a distribution of a physical quantity such as energy or momentum. The study of particle spectra allows us to see the global picture of particle production … Wikipedia

Representation theory of the Galilean group — In nonrelativistic quantum mechanics, an account can be given of the existence of mass and spin as follows:The spacetime symmetry group of nonrelativistic quantum mechanics is the Galilean group. In 3+1 dimensions, this is the subgroup of the… … Wikipedia
