111Modular form — In mathematics, a modular form is a (complex) analytic function on the upper half plane satisfying a certain kind of functional equation and growth condition. The theory of modular forms therefore belongs to complex analysis but the main… …
112orthogonal — orthogonality, n. orthogonally, adv. /awr thog euh nl/, adj. 1. Math. a. Also, orthographic. pertaining to or involving right angles or perpendiculars: an orthogonal projection. b. (of a system of real functions) defined so that the integral of… …
113Magnitude — may refer to: In mathematics: Magnitude (mathematics), the relative size of a mathematical object Magnitude (vector), a term for the size or length of a vector Scalar (mathematics), a quantity defined only by its magnitude Euclidean vector, a… …
114Cluster decomposition theorem — In physics, the cluster decomposition theorem guarantees locality in quantum field theory. According to this theorem, the vacuum expectation value of a product of many operators each of them being either in region A or in region B where A and B… …
115Argument (complex analysis) — Arg (mathematics) redirects here. For argument of a function, see Argument of a function. Figure 1. This Argand diagram represents the complex numbers lying on a plane. For each point on the plane, arg is the function which returns the angle φ.… …
116Unitary operator — For unitarity in physics, see unitarity (physics). In functional analysis, a branch of mathematics, a unitary operator (not to be confused with a unity operator) is a bounded linear operator U : H → H on a Hilbert space H… …
117Thales' theorem — In geometry, Thales theorem (named after Thales of Miletus) states that if A, B and C are points on a circle where the line AC is a diameter of the circle, then the angle ABC is a right angle. Thales theorem is a special case of the inscribed… …
118Parseval's identity — In mathematical analysis, Parseval s identity is a fundamental result on the summability of the Fourier series of a function. Geometrically, it is the Pythagorean theorem for inner product spaces. Informally, the identity asserts that the sum of… …
