# 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.

 stationary-processes× 62 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… coherent-sheaves× 62 In mathematics, especially in algebraic geometry and the theory of complex manifolds, coherent sheaves are a specific class of sheaves having particularly manageable properties closely linked to the g… invariance× 62 called invariant if, given some steps that alter the object, always remains, no matter what steps are used in what order. experimental-mathematics× 62 The utilization of advanced computing technology in mathematical research: new mathematical results discovered partly or entirely with the aid of computer-based tools. faq× 62 meant for questions which are generalized forms of questions which get asked frequently. See tag details for more information. graph-laplacian× 61 An simple graph has a symmetric matrix L = D - A associated with it called the Laplacian matrix, where D is the diagonal matrix of degrees and A is the adjacency matrix, often studied for its spectrum… dimensional-analysis× 61 The study of the relationships between physical quantities by identifying their units of measure and fundamental dimensions. It is used to convert from one set of units to others such as from miles p… algorithmic-game-theory× 61 an area in the intersection of game theory and algorithm design, whose objective is to design algorithms in strategic environments.

Typically the corresponding "fo… pell-type-equations× 56 Questions on finding integer solutions to a certain kind of bivariate equations. parity× 56 a mathematical term that describes the property of an integer's inclusion in one of two categories: even or odd. An integer is even if it is 'evenly divisible' by two and odd if it is not ev… associativity× 56 the property shared by many binary operations including group operations. For a binary operation $\cdot$, associativity holds if $(x\cdot y)\cdot z = x \cdot(y\cdot z)$. complex-manifolds× 56 For questions about complex manifolds. chebyshev-polynomials× 55 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. euler-lagrange-equation× 55 In calculus of variations, the Euler–Lagrange equation, Euler's equation, or Lagrange's equation, is a second-order partial differential equation whose solutions are the functions for which a given fu… gradient-flows× 55 An ordinary differential equation that generalizes the notion of "path of steepest descent."
