 z-transform× 20 a discrete analogue to the Laplace transform, in that it maps a time domain signal into a representation in complex frequency plane. magma× 20 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.) moebius-inversion× 20 For questions related to Moebius inversion and its applications. transcendence-theory× 19 A brief study of transcendental numbers and algebraic independence theories; currently an on-development branch of mathematics with a lot of open problems. linear-approximation× 19 hamiltonian-path× 19 group-extensions× 19 complex-manifolds× 19 chaotic-systems× 19 vector-lattices× 19 For questions about vector lattices (aka. Riesz spaces; a type of vector space equipped with a partial order), Banach lattices and similar topics. chebyshev-polynomials× 18 In mathematics the Chebyshev polynomials, named after Pafnuty Chebyshev, are a sequence of orthogonal polynomials which are related to de Moivre's formula and which can be defined recursively. almost-everywhere× 18 For questions about the concept of "almost everywhere", that is, questions about properties which holds everywhere, except on a set of measure $0$. This is involved in probability theory as well as in… connections× 18 descent× 18 differential-algebra× 18 scoring-algorithm× 18 matrix-decomposition× 18 octonions× 18 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. real-algebraic-geometry× 18 pro-p-groups× 17 For questions concerning pro-$p$ groups. These groups arise naturally in topology, algebraic number theory or Galois theory and are a special case of pro-finite groups. q-series× 17 primorial× 17 For problems involving either the product of the first n primes or the product of all primes up to and including n. profinite-groups× 17 For questions regarding profinite groups and their properties. percentages× 17 a number or ratio expressed as a fraction of $100$. It is often denoted using the percent sign, "$\%$", or the abbreviation "$\mathrm{pct}$." -Wikipedia. Percentages are used when desc… orthogonality× 17 span× 17 distribution-tails× 17 bipartite-graph× 17 continuous-homomorphisms× 16 To be used with questions about continuous homomorphisms into a space carrying both a topological and an algebraic structure. singular-measures× 16 simpsons-rule× 16 For questions regarding Simpson's rule and its applications. semigroup-of-operators× 16 For questions related to theory of semigroups of linear operators and its applications to partial differential equations, stochastic processes such as Markov processes and other branches of mathematic… monty-hall× 16 a probability puzzle with a solution that is counterintuitive to many. naive-bayes× 16 moduli-space× 16 mixing× 16 For questions about mixing in ergodic or probability theory.
