Density Point

Density Point

 

in mathematics. A density point of a set is a point such that the ratio of the measure of the part of the set in the neighborhood to the measure of the neighborhood—the so-called relative measure of a neighborhood of the point—approaches unity as the neighborhood shrinks to the point. In any measurable set, points that are not density points form a set of measure zero. Density points are of interest in the study of the asymptotic or approximative behavior of a function when the function in the neighborhood of a given point is considered not over the entire domain of definition but over a set for which the point is a density point. This is the case, for example, in the study of asymptotic continuity and of the derivative and differential.

Some third-party ink and paper manufacturers give display-life predictions for their papers based on tests that assume prints will be displayed under 120 lux UV-filtered illumination, instead of the higher standard of 450 lux glass-filtered illumination employed by WIR, and use a single density point for measuring fading compared with the two density points that WIR measures; taken together, these differences in test methods result in claims of display-life ratings that are between 4 to 15 times greater than those given by WIR.
