open complex
41Open and closed maps — In topology, an open map is a function between two topological spaces which maps open sets to open sets.[1] That is, a function f : X → Y is open if for any open set U in X, the image f(U) is open in Y. Likewise, a closed map is a function… …
42Open world — For other uses, see Open world (disambiguation). An open world is a type of video game level design where a player can roam freely through a virtual world and is given considerable freedom in choosing how to approach objectives.[1] Video games… …
43Complex analytic space — In mathematics, a complex analytic space is a generalization of a complex manifold which allows the presence of singularities. Complex analytic spaces are locally ringed spaces which are locally isomorphic to local model spaces, where a local… …
44Open-air museums in Slovakia — Slovakia has around 14 open air museums, or skanzens, showcasing the country s folk traditions, architecture, and economic history. The museums include examples of traditional buildings and furnishings, and many offer demonstrations of… …
45Complex number — A complex number can be visually represented as a pair of numbers forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the square root of –1. A complex… …

47Complex analysis — Plot of the function f(x)=(x2 1)(x 2 i)2/(x2 + 2 + 2i). The hue represents the function argument, while the brightness represents the magnitude. Complex analysis, traditionally known as the theory of functions of a complex variable, is the branch …
48Complex systems — A visual, organizational map of complex systems science See also: Complex system Complex systems present problems in mathematical modelling. The equations from which complex system models are developed generally derive from statistical physics,… …
49Complex plane — Geometric representation of z and its conjugate in the complex plane. The distance along the light blue line from the origin to the point z is the modulus or absolute value of z. The angle φ is the argument of z. In mathematics …
50Open sentence — In mathematics, an open sentence (usually an equation or equality) is described as open in the sense that its truth value is meaningless until its variables are replaced with specific numbers, at which point the truth value can usually be… …
