# 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.

 Type to find tags:
 inversive-geometry× 35 Questions related to Inversive Geometry and its applications. transfinite-recursion× 35 Questions dealing with set-theoretic functions defined by transfinite recursion. topological-graph-theory× 35 For questions about topological graphs, flows, representation, planar, and book embeddings, geometric graphs, crossing numbers, coloring graphs, and other topics in topological graph theory. stable-homotopy-theory× 35 cauchy-principal-value× 35 Computation of Cauchy principal values of integrals. May be tied in with contour integration, but should be separate from definite-integrals. cellular-automata× 35 group-extensions× 35 vector-lattices× 35 For questions about vector lattices (aka. Riesz spaces; a type of vector space equipped with a partial order), Banach lattices and similar topics. finite-automata× 34 undergraduate-research× 34 symplectic-linear-algebra× 34 Questions about vector spaces equipped with a symplectic form, a non-degenerate, skew-symmetric bilinear form. ricci-flow× 34 The Ricci flow on a Riemannian manifold $(M,g)$ is determined by the geometric evolution equation $\partial_t g_{ij} = -2R_{ij}$ where $R_{ij}$ is the Ricci curvature. The Ricci flow is the main ingre… rationality-testing× 34 For questions on determining whether a number is rational, and related problems. If applicable, use this tag instead of (rational-numbers) and (irrational-numbers). Consider adding a tag (radicals) or… l-functions× 34 music-theory× 34 nonclassical-logic× 33 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. moebius-transformation× 33 For questions about the geometry, complex-analytic, and group-theoretic properties of the Möbius transformations (linear fractional transformations) $z \mapsto \frac{az + b}{cz + d}$ of the complex pl… profinite-groups× 33 For questions regarding profinite groups and their properties. social-choice-theory× 33 For questions regarding the formal analysis of collective decision problems. galois-cohomology× 33 fractional-part× 32 For questions related to the fractional part of a number. chaotic-systems× 32 coalgebras× 32 probabilistic-method× 32 Probabilistic methods prove existence results in a nonconstructive fashion, by showing the chance of randomly selecting a solution is greater than zero. real-algebraic-geometry× 32 least-common-multiple× 32 For questions about the least common multiple of a collection of numbers (or more generally, elements of a commutative ring). kolmogorov-complexity× 32 Kolmogorov complexity concerns the size of the shortest program that generates a given string. percolation× 32 Percolation theory describes the behavior of connected clusters in a random graph. localization× 31 For questions regarding the process, consequences, and stability of localizing algebraic structures such as rings, categories, and modules. Not for use with local topological spaces. euler-product× 31 For questions on Euler products, an expansion of a Dirichlet series into an infinite product indexed by prime numbers. indeterminate-forms× 31 If the expression obtained after any substitution during limit analysis does not give enough information to determine the original limit, it is known as an indeterminate form. integral-dependence× 30 moebius-band× 30 a surface with only one side and only one boundary. The Möbius strip has the mathematical property of being non-orientable. It is named after the German mathematici… perfect-numbers× 30 Questions about or involving perfect numbers which are positive integers that are equal to the sum of their proper positive divisors. monty-hall× 30 a probability puzzle with a solution that is counterintuitive to many. octave× 30 For questions about Octave, a high-level interpreted language for numerical computations.
