Tags
A tag is a keyword or label that categorizes your question with other, similar questions.
For questions related to the rate of convergence (or the order of convergence). The rate of convergence of a convergent sequence are quantities that represent how quickly the sequence approaches its limit.

For basic questions in statistics involving the properties or use of standard error of the sample points present in a simple random sample.
123 questions
For questions about the Cauchy product, the discrete convolution of two sequences.

This tag is for questions about birth and death processes. These processes are a special case of the continuous-time Markov process where the state transitions are of only two types: "births", which increase the state variable by one and "deaths", which decrease the state by one and they are used to model the size of a population, queuing systems, the evolution of bacteria, the number of people with a disease within a population etc.

Questions about persistent homology, computational topology, discrete morse theory, and applied algebraic topology in general.
122 questions
For questions about Poisson manifolds, Poisson brackets and their geometric properties.

This is meant for questions which are generalized forms of questions which get asked frequently. See tag details for more information.
122 questions
Use this tag for questions related to the branch of number theory studying distribution laws of prime numbers among natural numbers.

Use this tag for questions concerning the notion of spectra in algebraic topology. Spectra are natural objects which arises when dealing with stable properties. For spectra of linear operators, please use the tag (spectral-theory) instead.
121 questions
For questions related to primary decomposition. In mathematics, every ideal can be decomposed as an intersection, called primary decomposition, of finitely many primary ideals (which are related to, but not quite the same as, powers of prime ideals).

A formula is in disjunctive normal form (DNF) if it is a disjunction of conjunctive clauses.
121 questions
Use this tag for questions related to Dirichlet convolution in number theory
121 questions
For questions on the octonions, a normed division algebra over the real numbers. It is a non-associative higher-dimensional analogue in the hierarchy of real, complex, and quaternionic numbers.

(Stub) The loop space is the function space consisting of all continuous maps from the circle into a topological space; the function space is equipped with the compact-open topology. It is studied in topology, especially homotopy theory.
120 questions
Use this tag for questions related to the bisection method, which is a root-finding method that repeatedly bisects an interval and then selects a subinterval in which a root must lie for further processing.
119 questions
A decision problem is a question (in some formal system) whose answer is either "yes" or "no".
118 questions
Use this tag in reference to questions concerning random variables following the Bernoulli distribution, including calculating quantities such as expectation, standard deviation, moments, as well as real world applications.
118 questions
For questions regarding the different ways to generate and verify theorems via specialized computer languages, algorithms, and other computer-aided tools.
118 questions
For questions related to metalogic. It is the study of the metatheory of logic. Whereas logic studies how logical systems can be used to construct valid and sound arguments, metalogic studies the properties of logical systems. Logic concerns the truths that may be derived using a logical system; metalogic concerns the truths that may be derived about the languages and systems that are used to express truths.
116 questions
For questions related to mapping class group. The mapping class group is a certain discrete group corresponding to symmetries of the space.
116 questions
A topological space with a single nonzero homotopy group. Use in conjunction with (algebraic-topology), (homotopy-theory), (homology-cohomology) or (classifying-spaces).
116 questions
Quantifier elimination is the removal of all quantifiers (universal and existential) from a quantified formula in order to produce an equivalent quantifier-free formula.
115 questions
The Pochhammer symbol is notation used for both rising and falling factorials, e.g. in defining basic hypergeometric series and related special functions. This tag is also appropriate for questions about the $q$-Pochhammer symbol, which plays a similar role in defining $q$-hypergeometric series, etc.

Mental arithmetic comprises arithmetical calculations using only the human brain, with no help from calculators, computers, or pen and paper.
115 questions
Questions that are based on, use, or include the q-series in their content or solutions.
114 questions
This tag is for questions regarding to pseudo-differential operators, which are generalizations of differential operators and Fourier multipliers. It satisfies estimates for the derivatives analogous to the estimates for derivatives of polynomials, which are symbols of differential operators.
114 questions
For questions related to p-value. In statistics, the p-value is the probability of obtaining results at least as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct.
114 questions
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.
114 questions
For questions about a category where the Hom-spaces have additional structure. Should probably be used with the general (category-theory) tag.
114 questions
In many questions the problem of determining bounds of integration in multiple integrals is a major part of what an answer needs to deal with, and in surprisingly many questions it is the only issue. This tag is for such occasions.
114 questions
In logic a Hilbert calculus, sometimes called Hilbert system, Hilbert-style deductive system or Hilbert–Ackermann system, is a type of system of formal deduction attributed to Gottlob Frege and David Hilbert. These deductive systems are most often studied for propositional and first-order logic.
