Fixed point
In mathematics, a fixed point of a function is a point that is mapped to itself by the function. A set of fixed points is sometimes called a fixed set. That is to say, c is a fixed point of the function f(x) if and only if f = c. This means f = fn = c, an important terminating consideration when recursively computing f. For example, if f is defined on the real numbers by then 2 is a fixed point of f, because f = 2. Not all functions have fixed points: for example, if f is a function defined on the real numbers as f(x) = x + 1, then it has no fixed points, since x is never equal to x + 1 for any real number. In graphical terms, a fixed point means the point is on the line y = x, or in other words the graph of f has a point in common with that line. Points which come back to the same value after a finite number of iterations of the function are known as periodic points; a fixed point is a periodic point with period equal to one. In projective geometry, a fixed point of a collineation is called a double point.
