# 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:
 infimum× 63 For questions on infima. branch-cuts× 63 derived-functors× 63 error-propagation× 62 For questions on propagation of errors. latin-square× 62 For questions on or pertaining to Latin squares. monoidal-categories× 62 modal-logic× 62 Questions relating to deductions relating to the expressions "it is necessary that" and "it is possible that" parameter-estimation× 62 quantum-field-theory× 62 quotient-spaces× 62 krull-dimension× 61 For questions about or related to the Krull dimension. higher-category-theory× 61 binary-operations× 61 a map $\ast : X \times X \to X$. Usually, we denote $\ast(x, y)$ by $x\ast y$. clustering× 60 grouping (partitioning) a set of objects so that items in the same group are more similar to each other than to items in different groups, where the notion of similarity may be variously… formal-grammar× 60 simplex× 60 spherical-harmonics× 60 Questions on spherical harmonics, a set of basis functions that satisfy an orthogonality relation over the sphere. topological-k-theory× 60 a generalized cohomology theory, for which $K_0(X)$ is the Grothendieck group of isomorphism classes of vector bundles over topological space $X$. See also [tag:algebraic-k-the… spectral-sequences× 59 (STUB) A method of computing homology groups by taking a sequence of approximations. Particularly useful in algebraic topology. meta-math× 59 the term for the theory in which mathematics is formalized (often PA, ZFC or similar theories). Meta-mathematical statements are statements which are evaluated at the level of the meta-… noncommutative-geometry× 59 a study of noncomutative algebras from geometrical point of view. The motivation of this approach is Gelfand representation theorem, which shows that every commutative C*-al… matrix-decomposition× 59 hash-function× 59 For questions about hash functions: functions from a big set to a smaller one such that the same output $f(x_1)=f(x_2)$ for different input $x_1\ne x_2$ is unlikely, especially if $x_2$ differs from $… constants× 59 For questions about mathematical constants, that are "significantly interesting in some way". optimal-control× 58 uniform-integrability× 58 For questions about families of uniformly integrable random variables. Use the tags [tag: measure-theory] or [tag: probablity-theory]. unit-of-measure× 58 For questions related to conversion of units. median× 57 sieve-theory× 57 Sieve theory deals with number theoretic sieves, and sifted sets. E.g. the Sieve of Eratosthenes, Brun sieve, and other modern sives. decision-theory× 57 For questions regarding formal decision problems. In contrast, questions involving strategic aspects (where the solution depends on the behavior of others) are discussed in game theory. dihedral-groups× 57 For questions on dihedral groups, the group of symmetries of a regular polygon, including both rotations and reflections lambert-w× 57 For questions related to the Lambert-W or product log function. This is the inverse function of$f(z) = ze^z\$. geometric-algebras× 57 Clifford algebras over the real numbers. They are applied in geometry and theoretical physics. infinite-groups× 56 minimal-polynomials× 56 the lowest order monic polynomial satisfied by an object, such as a matrix or an algebraic element over a field. matrix-rank× 56 For questions regarding the rank of matrices in linear algebra.
