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:
 research× 59 levy-processes× 58 Question related to Lévy processes, i.e. stochastically continuous processes with independent, stationary increments. primitive-roots× 58 For questions about primitive roots in modular arithmetic, index calculus, and applications in cryptography. For questions about primitive roots of unity, use the (roots-of-unity) tag instead. algorithmic-game-theory× 58 collatz× 57 Dynamics of the iterated map $n \to 3n+1$ if $n$ is odd and $n \to \frac n2$ if $n$ is even. Generalizations to $n \to 3n-1$ or $n \to 5n+1$ or even to $n \to pn+q$ . Other names are "$3x+1$-proble… poisson-distribution× 57 utility× 57 A tag for all questions involving a type of utility function. finite-element-method× 56 A method of obtaining (numerically) approximate solutions to (usually) differential equations. It consists of a method of discretization splitting the domain into disjoint subdomains over each of whic… hopf-algebras× 56 For questions about Hopf algebras and related concepts, such as quantum groups. complex-dynamics× 55 the study of dynamical systems of functions over complex numbers. rubiks-cube× 55 Questions on the mathematics behind the famed toy invented by Ernő Rubik. translation-request× 55 for requests to translate written mathematical material from one language to another. laplacian× 54 The properties of the Laplace differential operator, denoted $\Delta$ or $\nabla^2$, and defined as the divergence of the gradient. For Laplace equation, see (harmonic-functions) model-categories× 54 categories with three distinguished classes of morphisms: the weak equivalences, the fibrations and the cofibrations. They provide a natural setting for [tag:homotopy-theory] in a… mathematicians× 54 Questions about mathematicians and their lives. noise× 54 invariance× 54 hodge-theory× 53 The study of relations between, one the one hand, the topology of a smooth manifold as encoded in the cohomology groups, and on the other, the set of solutions to the Laplace operator on differential … faq× 53 meant for questions which are generalized forms of questions which get asked frequently. See tag details for more information. artificial-intelligence× 53 For questions about artificial intelligence. bifurcation× 53 separation-axioms× 53 properties of topological space which, roughly speaking, say in what way two points, a point and a closed set, or two closed sets can be "separated". rigid-transformation× 53 mappings from one reference frame to another reference frame in the Euclidean space $\mathbb R^n$. They comprise translation, rotation (and sometimes reflection). More for… random-functions× 52 quadrilateral× 51 For questions about general quadrilaterals (including parallelograms, trapezoids, rhombi) and their properties. nets× 51 a generalization of a sequence where a directed set is used as the index set instead of positive integers. Convergence of nets can be defined in a similar way as convergence of sequences. … multiplicative-function× 51 In number theory, a multiplicative function is a function defined on positive integers such that f(ab)=f(a)f(b) for a,b coprime. E.g. Euler's totient function, sum of divisors and number of divisor… minimal-surfaces× 51 Question on minimal surfaces, or surfaces that have zero mean curvature. automorphic-forms× 51 a generalization of the idea of periodic functions in Euclidean space to general topological groups. coherent-sheaves× 50 dedekind-domain× 50 experimental-mathematics× 50 The utilization of advanced computing technology in mathematical research: new mathematical results discovered partly or entirely with the aid of computer-based tools. stationary-processes× 50 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… z-transform× 49 a discrete analogue to the Laplace transform, in that it maps a time domain signal into a representation in complex frequency plane. mean-square-error× 49 dimensional-analysis× 49
