WebIn the mathematical areas of order and lattice theory, the Knaster–Tarski theorem, named after Bronisław Knaster and Alfred Tarski, states the following: Let ( L, ≤) be a complete lattice and let f : L → L be an monotonic function (w.r.t. ≤ ). Then the set of fixed points of f in L also forms a complete lattice under ≤ . WebFor example, the cosine function is continuous in [−1,1] and maps it into [−1, 1], and thus must have a fixed point.
