Fixed points
In domain theory, the notion and terminology of fixed points is generalized to a partial order. Let ≤ be a partial order over a set X and let f: X → X be a function over X. Then a prefixed point (also spelled pre-fixed point, sometimes shortened to prefixpoint or pre-fixpoint) of f is any p such that f(p) ≤ p. Analogously, a postfixed point of f is any p such that p ≤ f(p). The opposite usage occasionally appears. Malkis justifies the definition presented here as follows: "since f is before … WebApr 13, 2024 · Such probability mistakes betray that at least some of us often do not grasp necessary conditions on the concept of probability, what we call probability fixed points. Our case study that illustrates this phenomenon in action is the recent COVID-19 pandemic.

Every non-identity Möbius transformation has two fixed points, on the Riemann sphere. Note that the fixed points are counted here with multiplicity; the parabolic transformations are those where the fixed points coincide. Either or both of these fixed points may be the point at infinity.
