101List of permutation topics — This is a list of topics on mathematical permutations.*Alternating group *Alternating permutation *Bijection *Circular shift *Combination *Cycle index *Cycle notation *Cyclic order *Cyclic permutation *Derangement *Even and odd permutations… …
102Angular momentum operator — In quantum mechanics, the angular momentum operator is an operator analogous to classical angular momentum. The angular momentum operator plays a central role in the theory of atomic physics and other quantum problems involving rotational… …
103Leibniz formula for determinants — In algebra, the Leibniz formula expresses the determinant of a square matrix A = (a {ij}) {i,j = 1, dots, n} in terms of permutations of the matrix elements. Named in honor of Gottfried Leibniz, the formula is:det(A) = sum {sigma in S n}… …
104Alternatives to general relativity — are physical theories that attempt to describe the phenomena of gravitation in competition to Einstein s theory of general relativity.There have been many different attempts at constructing an ideal theory of gravity. These attempts can be split… …
105Molecular Hamiltonian — In atomic, molecular, and optical physics as well as in quantum chemistry, molecular Hamiltonian is the name given to the Hamiltonian representing the energy of the electrons and nuclei in a molecule. This Hermitian operator and the associated… …
106Bianchi classification — In mathematics, the Bianchi classification, named for Luigi Bianchi, is a classification of the 3 dimensional real Lie algebras into 11 classes, 9 of which are single groups and two of which have a continuum of isomorphism classes. (Sometimes two …
107Nahm equations — The Nahm equations are a system of ordinary differential equations introduced by Werner Nahm in the context of the Nahm transform – an alternative to Ward s twistor construction of monopoles. The Nahm equations are formally analogous to the… …
108Anti-symmetric operator — In quantum mechanics, a raising or lowering operator (collectively known as ladder operators) is an operator that increases or decreases the eigenvalue of another operator. In quantum mechanics, the raising operator is sometimes called the… …
109Classical electromagnetism and special relativity — This article is about the contribution of special relativity to the modern theory of classical electromagnetism. For the contribution of classical electromagnetism to the development of special relativity, see History of special relativity. For a …
110Spin (physics) — This article is about spin in quantum mechanics. For rotation in classical mechanics, see angular momentum. In quantum mechanics and particle physics, spin is a fundamental characteristic property of elementary particles, composite particles… …
