Fixed point (mathematics)

A fixed point (sometimes shortened to fixpoint, also known as an invariant point) is a value that does not change under a given transformation. Specifically, in mathematics, a fixed point of a function is an element that is mapped to itself by the function. In physics, the term fixed point can refer to a temperature that can be used as a reproducible reference point, usually defined by a phase change or triple point. (Wikipedia).

Fixed and Periodic Points | Nathan Dalaklis

Fixed Points and Periodic points are two mathematical objects that come up all over the place in Dynamical systems, Differential equations, and surprisingly in Topology as well. In these videos, I introduce the concepts of fixed points and periodic points and gradually build to a proof of

What are opposite rays

👉 Learn essential definitions of points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A plane contains infinite number of lines. A ray is a li

The Geometry of Democracy

What is the best way to design a voting system? Governments and other institutions have been experimenting for decades with all sorts of different systems, "ranked choice" being a trendy system recently. In the 1950's, mathematician and economist Kenneth Arrow laid out a very mild set of c

Giuseppe De Nittis : Topological nature of the Fu-Kane-Mele invariants

Abstract: Condensed matter electronic systems endowed with odd time-reversal symmetry (TRS) (a.k.a. class AII topological insulators) show topologically protected phases which are described by an invariant known as Fu-Kane-Mele index. The construction of this in- variant, in its original f

Calculus lesson 15 - Locating stationary points on a curve

In this lesson we talk about how to locate stationary points on a curve, by differentiating the equation of the curve and making the derivative equal to zero, then solving for x. For more practice questions, answers and other learning support materials, visit www.magicmonktutorials.com
