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:
 dedekind-domain× 38 coherent-sheaves× 37 galois-representations× 37 gauge-theory× 37 inverse-problems× 37 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… legendre-polynomial× 37 For questions about Legendre polynomials, which are solutions to a particular differential equation that frequently arises in physics. stationary-processes× 37 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… toric-geometry× 37 universal-property× 37 hamiltonian-path× 36 extrapolation× 36 For question on extrapolation, the process of estimating, beyond the original observation interval. fibration× 36 relation-algebra× 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.) quadrilateral× 35 For questions about general quadrilaterals (including parallelograms, trapezoids, rhombi) and their properties. undergraduate-research× 35 poker× 34 a card game with several variants (Draw, Texas Hold'em, ...), the common goal being to collect face value patterns such as "four of a kind", "full house" or "straight" or all of a suit ("flus… z-transform× 34 a discrete analogue to the Laplace transform, in that it maps a time domain signal into a representation in complex frequency plane. connections× 34 blowup× 34 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… calendar-computations× 34 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× 34 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… ceiling-function× 34 The function that maps a real number x to the smallest integer not less than x. (See also (floor-function).) gauss-sums× 33 For questions on Gauss sums, a particular kind of finite sum of roots of unity. k-theory× 33 intuitionism× 33 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… parity× 33 positive-characteristic× 32 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 … ricci-flow× 32 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… span× 32 chemistry× 32 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… collision-detection× 32 coxeter-groups× 32 For questions about Coxeter groups, an abstract group that admits a formal description in terms of reflections. voting-theory× 32 For questions regarding the mathematical analysis of voting systems and behavior. Examples include the median voter theorem or the Condorcet jury theorems. sheaf-cohomology× 31
