7Closed and exact differential forms — In mathematics, especially vector calculus and differential topology, a closed form is a differential form α whose exterior derivative is zero (dα = 0), and an exact form is a differential form that is the exterior derivative of another …
8Closed-loop transfer function — A closed loop transfer function in control theory is a mathematical expression (algorithm) describing the net result of the effects of a closed (feedback) loop on the input signal to the circuits enclosed by the loop. Contents 1 Overview 2… …
9Closed class — In linguistics, a closed class (or closed word class) is a word class to which no new items can normally be added, and that usually contains a relatively small number of items. Typical closed classes found in many languages are adpositions… …
10Closed convex function — In mathematics, a convex function is called closed if its epigraph is a closed set. Properties A closed convex function f is the pointwise supremum of the collection of all affine functions h such that h≤f. References Rockafellar, R. Tyrell,… …
