Degeneracy — may refer to: Degeneration In science and mathematics: Degeneracy (statistical mechanics), a property of quantum states sharing the same energy levels Degeneracy (mathematics), a limiting case in which a class of object changes its nature so as… … Wikipedia
Degeneracy (graph theory) — In graph theory, a k degenerate graph is an undirected graph in which every subgraph has a vertex of degree at most k: that is, some vertex in the subgraph touches k or fewer of the subgraph s edges. The degeneracy of a graph is the smallest… … Wikipedia
Degeneracy (biology) — Within biological systems, degeneracy refers to circumstances where structurally dissimilar components/modules/pathways can perform similar functions (i.e. are effectively interchangeable) under certain conditions, but perform distinct functions… … Wikipedia
Degeneracy (mathematics) — For the degeneracy of a graph, see degeneracy (graph theory). This article is about degeneracy in mathematics. For other uses, see Degeneracy. In mathematics, a degenerate case is a limiting case in which a class of object changes its nature so… … Wikipedia
Perturbation theory (quantum mechanics) — In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a … Wikipedia
Nerve (category theory) — In category theory, the nerve N(C) of a small category C is a simplicial set constructed from the objects and morphisms of C. The geometric realization of this simplicial set is a topological space, called the classifying space of the category C … Wikipedia
Perturbation theory — This article describes perturbation theory as a general mathematical method. For perturbation theory as applied to quantum mechanics, see perturbation theory (quantum mechanics). Perturbation theory comprises mathematical methods that are used to … Wikipedia
Catastrophe theory — This article refers to the study of dynamical systems. For other meanings, see catastrophe. In mathematics, catastrophe theory is a branch of bifurcation theory in the study of dynamical systems; it is also a particular special case of more… … Wikipedia
