# 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:
 manifolds-with-boundary× 56 typically defined to be without boundaries (every point has a neighbourhood homeomorphic to an Euclidean open disc). Use this tag for the manifolds with boundaries, as well as manifolds … magma-cas× 56 a computer algebra system distributed by the University of Sydney, and designed for solving problems in algebra, number theory, geometry and combinatorics. monomial-ideals× 56 magma× 55 a set together with a binary operation on this set. (For questions about the computer algebra system named Magma, use the [magma-cas] tag instead.) searching× 55 For questions about various search algorithms. formal-power-series× 55 elliptic-equations× 55 For questions about elliptic partial differential equations. If your question is specific to the Laplace equation, see (harmonic-functions). cayley-graphs× 55 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 $S\subseteq G$. collision-detection× 55 stereographic-projections× 55 For question about stereographic projection, a particular mapping that projects a sphere onto a plane. birational-geometry× 54 simplicial-complex× 54 singular-integrals× 54 integral operators with kernel $K:\mathbb{R}^n\times\mathbb{R}^n\to\mathbb{R}$ that is not defined on the diagonal $x=y.$ This tag is for questions related to singular integrals… profinite-groups× 54 For questions regarding profinite groups and their properties. power-towers× 54 For questions pertaining to power towers: expressions like a^(b^(c^d))), which result from iterated exponentiation. The "hyperoperation" tag may be appropriate, too. percentile× 53 A value representing the lowest $n$ percent of the values in a data set or of the possible values of a random variable. cauchy-principal-value× 53 Computation of Cauchy principal values of integrals. May be tied in with contour integration, but should be separate from definite-integrals. provability× 52 quiver× 52 an oriented graph which might contain multiple edges and loops. The terminology is used in representation-theory of finite dimensional algebras, where one considers functors from this grap… subgradient× 52 kolmogorov-complexity× 51 Kolmogorov complexity concerns the size of the shortest program that generates a given string. legendre-symbol× 51 For questions involving the Legendre symbol, $\genfrac{(}{)}{}{}{a}{p}$ for integer $a$ and prime $p$. coalgebras× 51 function-fields× 50 magic-square× 50 an arrangement of $n^2$ numbers, usually distinct integers, in a square, such that the n numbers in all rows, all columns, and both diagonals sum to the same constant. ht… maxima-software× 50 For questions concerning the open source computational software program Maxima. multivalued-functions× 50 In Mathematics, set theory, a Multivalued function is defined as a left-total relation (that is, every input is associated with at least one output) in which at least one input is associated with mult… quasicoherent-sheaves× 50 voting-theory× 50 For questions regarding the mathematical analysis of voting systems and behavior. Examples include the median voter theorem or the Condorcet jury theorems. rngs× 49 an associative ring without necessarily having a multiplicative identity (rng = ring - $i$dentity). solid-angle× 49 mobius-inversion× 49 For questions related to Moebius inversion and its applications. hardy-spaces× 49 For questions about Hardy spaces. Use the other related tag like (tag: complex-analysis) or (operator-theory). centroid× 49 data-mining× 49 functional-calculus× 48 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…
