# 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:
 mathematicians× 41 Questions about mathematicians and their lives. stationary-processes× 41 For questions about strictly stationary or stationary in the wide sense sequences or processes. Questions about deterministic stationary processes (in the case of discrete dynamical systems) are welco… prime-twins× 40 For questions on prime twins. dedekind-domain× 40 transformational-geometry× 40 fuzzy-logic× 39 inverse-problems× 39 Inverse problems involve for example reconstruction of an object based on physical measurements and finding a best model/parameters out of a family given observed data. Typically the corresponding "fo… extrapolation× 38 For question on extrapolation, the process of estimating, beyond the original observation interval. fibration× 38 coherent-sheaves× 38 ceiling-function× 38 The function that maps a real number x to the smallest integer not less than x. (See also (floor-function).) quadrilateral× 38 For questions about general quadrilaterals (including parallelograms, trapezoids, rhombi) and their properties. rngs× 38 an associative ring without necessarily having a multiplicative identity (rng = ring - $i$dentity). universal-property× 38 toric-geometry× 37 parity× 37 blowup× 37 A technique in geometry (especially algebraic and differential, and by extension to study of pseudo-differential operators) for resolution of singularities. Not to be confused with the formation of si… connections× 37 galois-representations× 37 gauge-theory× 37 intuitionism× 36 In the philosophy of mathematics, intuitionism, or neointuitionism (opposed to preintuitionism), is an approach where mathematics is considered to be purely the result of the constructive mental activ… linear-transformations× 36 z-transform× 36 a discrete analogue to the Laplace transform, in that it maps a time domain signal into a representation in complex frequency plane. undergraduate-research× 36 voting-theory× 35 For questions regarding the mathematical analysis of voting systems and behavior. Examples include the median voter theorem or the Condorcet jury theorems. relation-algebra× 35 sheaf-cohomology× 35 linear-groups× 35 a group $G$ whose elements are invertible $n \times n$ matrices over a field $F$. magma× 35 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.) positive-characteristic× 35 For questions involving rings of positive characteristic, particularly those questions whose statements and hypotheses heavily rely on positive characteristic. Consider using the ring-theory tag for … calendar-computations× 35 for questions about combinatorial and computational issues with regards to calendar systems. A typical, well-known mathematical result in this direction is John Conway's Doomsday Algorithm… classifying-spaces× 35 A classifying space $BG$ of a topological group $G$ is the quotient of a weakly contractible space $EG$ by a free action of $G$. When $G$ is a discrete group $BG$ has homotopy type of $K(G,1)$ and (co… chemistry× 35 Questions related to mathematical chemistry which include application of mathematics to problems in chemistry and the development of mathematical methods suitable for such applications and for the for… bipartite-graph× 34 collision-detection× 34 coxeter-groups× 34 For questions about Coxeter groups, an abstract group that admits a formal description in terms of reflections.
