81Dihedral group of order 6 — The smallest non abelian group has 6 elements. It is a dihedral group with notation D3 (or D6, both are used) and the symmetric group of degree 3, with notation S3. This page illustrates many group concepts using this group as example. Contents 1 …
82Wiener–Hopf method — The Wiener–Hopf method is a mathematical technique widely used in applied mathematics. It was initially developed by Norbert Wiener and Eberhard Hopf as a method to solve systems of integral equations, but has found wider use in solving two… …

84Jordan's lemma — in complex analysis is a powerful tool used frequently when evaluating contour integrals, and real integrals from ∞ to +∞.Consider a function of the form: ::f(z)=e^{iaz} g(z),Jordan s Lemma states that::lim {R o infty} int {C 1} f(z), dz = 0 quad …
85Anti de Sitter space — In mathematics and physics, n dimensional anti de Sitter space, sometimes written AdS n, is a maximally symmetric Lorentzian manifold with constant negative scalar curvature. It is the Lorentzian analog of n dimensional hyperbolic space, just as… …
86Hyperfunction — In mathematics, hyperfunctions are generalizations of functions, as a jump from one holomorphic function to another at a boundary, and can be thought of informally as distributions of infinite order. Hyperfunctions were introduced by Mikio Sato… …
87Hyperbolic geometry — Lines through a given point P and asymptotic to line R. A triangle immersed in a saddle shape plane (a hyperbolic paraboloid), as well as two diverging ultraparall …
88Fundamental pair of periods — In mathematics, a fundamental pair of periods is an ordered pair of complex numbers that define a lattice in the complex plane. This type of lattice is the underlying object with which elliptic functions and modular forms are defined. Although… …
89Complex logarithm — A single branch of the complex logarithm. The hue of the color is used to show the arg (polar coordinate angle) of the complex logarithm. The saturation (intensity) of the color is used to show the modulus of the complex logarithm. The page with… …
90Surface — This article discusses surfaces from the point of view of topology. For other uses, see Differential geometry of surfaces, algebraic surface, and Surface (disambiguation). An open surface with X , Y , and Z contours shown. In mathematics,… …
