91Special unitary group — In mathematics, the special unitary group of degree n , denoted SU( n ), is the group of n times; n unitary matrices with determinant 1. The group operation is that of matrix multiplication. The special unitary group is a subgroup of the unitary… …
92Linear functional — This article deals with linear maps from a vector space to its field of scalars.  These maps may be functionals in the traditional sense of functions of functions, but this is not necessarily the case. In linear algebra, a linear functional… …
93Homogeneous space — In mathematics, particularly in the theories of Lie groups, algebraic groups and topological groups, a homogeneous space for a group G is a non empty manifold or topological space X on which G acts continuously by symmetry in a transitive way. A… …
94Multiple cross products — is a mathematical term.Using multiple cross productsIn mathematics, one must be careful when using multiple cross products. The cross product operation is not associative: we have in general :( A times; B ) times; C ne; A times;( B times; C… …
95Lorentz covariance — In standard physics, Lorentz covariance is a key property of spacetime that follows from the special theory of relativity, where it applies globally. Local Lorentz covariance refers to Lorentz covariance applying only locally in an infinitesimal… …
96Antisymmetric tensor — In mathematics and theoretical physics, a tensor is antisymmetric on two indices i and j if it flips sign when the two indices are interchanged: An antisymmetric tensor is a tensor for which there are two indices on which it is antisymmetric. If… …
97Spin quantum number — In atomic physics, the spin quantum number is a quantum number that parameterizes the intrinsic angular momentum (or spin angular momentum, or simply spin) of a given particle. The spin quantum number is the fourth of a set of quantum numbers… …
98Feynman slash notation — In the study of Dirac fields in quantum field theory, Richard Feynman invented the convenient Feynman slash notation (less commonly known as the Dirac slash notation[1]). If A is a covariant vector (i.e., a 1 form), using the Einstein summation… …
99Rarita-Schwinger equation — In theoretical physics, the Rarita Schwinger equation is the relativistic field equation of spin 3/2 fermions. It is similar to the Dirac equation for spin 1/2 fermions. This equation was first introduced by William Rarita and Julian Schwinger in …
100Representation theory of the Lorentz group — The Lorentz group of theoretical physics has a variety of representations, corresponding to particles with integer and half integer spins in quantum field theory. These representations are normally constructed out of spinors.The group may also be …
