F A (I) centers have similar properties as regular F centers, whereas F A (II) centers cause two potential wells to form in the excited state due to the repositioning of a halide ion. Similar to the F A is the F B center, which consists of an F center with two neighbouring positive ions replaced by a positive ion of a different kind.

In probability theory and statistics, the F-distribution or F-ratio, also known as Snedecor's F distribution or the Fisher–Snedecor distribution (after Ronald Fisher and George W. Snedecor), is a continuous probability distribution that arises frequently as the null distribution of a test statistic, most notably in the analysis of variance (ANOVA) and other F-tests.

Fig. 1: The graph of the hyperelliptic curve : = where () = + + = (+) (+) ().. In algebraic geometry, a hyperelliptic curve is an algebraic curve of genus g > 1, given by an equation of the form + = where f(x) is a polynomial of degree n = 2g + 1 > 4 or n = 2g + 2 > 4 with n distinct roots, and h(x) is a polynomial of degree < g + 2 (if the characteristic of the ground field is not 2, one can ...
An FCurve (also written f-curve) is a function curve or the graph of a function.An example of a FCurve is a spline.. In the field of computer animation and especially in animation editors, e.g. Maya, an FCurve is an animation curve with a set of keyframes, which are represented as points, curve segments between keys, and tangents that control how curve segments enter and exit a key.
