# Tags

A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

 cellular-automata× 30 spherical-trigonometry× 30 real-algebraic-geometry× 30 pseudoinverse× 30 The operator $A^+$ which best approximates a solution to linear equations $Ax+b=0$ even if $A$ is singular. cayley-graphs× 29 graphs obtained from a group $G$ in a such way that vertices are elements of the group and edges are added using some generating set $S\subseteq G$. fractional-part× 29 For questions related to the fractional part of a number. geometric-series× 29 For questions about or involving geometric series, a series where successive terms have a common ratio. integral-dependence× 29 topological-graph-theory× 29 For questions about topological graphs, flows, representation, planar, and book embeddings, geometric graphs, crossing numbers, coloring graphs, and other topics in topological graph theory. vector-lattices× 29 For questions about vector lattices (aka. Riesz spaces; a type of vector space equipped with a partial order), Banach lattices and similar topics. descent× 28 probabilistic-method× 28 Probabilistic methods prove existence results in a nonconstructive fashion, by showing the chance of randomly selecting a solution is greater than zero. profinite-groups× 28 For questions regarding profinite groups and their properties. q-analogs× 27 for questions pretaining to q-analogs of functions, for example q-Binomials, $q$-derivatives, the q-theta function, the q-Pochammer symbol, etc. pronunciation× 27 Questions on the pronunciation of mathematical terms and notation. percolation× 27 Percolation theory describes the behavior of connected clusters in a random graph. octave× 27 For questions about Octave, a high-level interpreted language for numerical computations. monads× 27 a functor from a category to itself together with two natural transformations, commonly called μ (the "multiplication") and η (the "unit"), satisfying conditions that make μ monoidal and η … mixing× 27 For questions about mixing in ergodic or probability theory. loop-spaces× 27 the function space consisting of all continuous maps from the circle into a topological space; the function space is equipped with the compact-open topology. It is studied in … kolmogorov-complexity× 27 Kolmogorov complexity concerns the size of the shortest program that generates a given string. laplace-expansion× 27 l-functions× 27 continuous-homomorphisms× 27 To be used with questions about continuous homomorphisms into a space carrying both a topological and an algebraic structure. transcendence-theory× 27 A brief study of transcendental numbers and algebraic independence theories; currently an on-development branch of mathematics with a lot of open problems. theorem-provers× 27 Automatic proof checkers verify the validity of formal proofs, while proof assistants aid in the construction of formal proofs. Some popular systems: Mizar, Coq, Isabelle. For automated theorem prove… stability-in-odes× 26 For questions concerning stability of equilibria and of other solutions of ordinary differential equations and their systems. cobordism× 26 Literally "together boundary", a cobordism is a relation between two compact manifolds stating that their disjoint union forms the boundary of a higher dimensional manifold. This defines a equivalence… functional-calculus× 26 Functional calculus allows the evaluation of a function applied to a linear operator or a matrix. The function could be a polynomial, a holomorphic function, a continuous function or a measurable func… equidistribution× 26 said to be equidistributed, or uniformly distributed, if the proportion of terms falling in a subinterval is proportional to the length of that interval. local-cohomology× 26 moebius-inversion× 26 For questions related to Moebius inversion and its applications. monty-hall× 26 a probability puzzle with a solution that is counterintuitive to many. nonclassical-logic× 26 For questions about three-valued logic and other non-classical logics. Please use the more specific tags 'modal-logic' and 'fuzzy-logic' instead of this tag if they apply. q-series× 25 platonic-solids× 25 a regular, convex polyhedron with congruent faces of regular polygons and the same number of faces meeting at each vertex.
