**Beam divergence**— The beam divergence of an electromagnetic beam is an angular measure of the increase in beam diameter with distance from the optical aperture or antenna aperture from which the electromagnetic beam emerges. The term is relevant only in the far… …102

**Jensen–Shannon divergence**— In probability theory and statistics, the Jensen Shannon divergence is a popular method of measuring the similarity between two probability distributions. It is also known as information radius (IRad) [cite book |author=Hinrich Schütze;… …103

**F-divergence**— In probability theory, an f divergence is a function I f ( P , Q ) that measures the difference between two probability distributions P and Q . The divergence is intuitively an average of the function f of the odds ratio given by P and Q .These… …106

**Point of divergence**— In discussion of counterfactual history, a divergence point (DP), also referred to as a departure point or point of divergence (POD), is a historical event with two possible postulated outcomes. Typically these represent the actual course of… …107

**Bregman divergence**— In mathematics Bregman divergence or Bregman distance is similar to a metric, but does not satisfy the triangle inequality nor symmetry. There are two ways in which Bregman divergences are important. Firstly, they generalize squared Euclidean… …108

**Théorème de flux-divergence**— En analyse vectorielle, le théorème de flux divergence, appelé aussi théorème de Green Ostrogradski, affirme l égalité entre l intégrale de la divergence d un champ vectoriel sur un volume dans et le flux de ce champ à travers la frontière du… …109

**Drag divergence Mach number**— The drag divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase[1]. This increase can… …110

**Infrared divergence**— In physics, an infrared divergence is a situation in which an integral, for example a Feynman diagram, diverges because of contributions of objects with very small energy approaching zero, or, equivalently, because of physical phenomena at very… …
