Divergence (disambiguation) — Divergence can refer to: In mathematics: Divergence, a function that associates a scalar with every point of a vector field Divergence (computer science), a computation which does not terminate (or terminates in an exceptional state) Divergence… … Wikipedia
Ultraviolet divergence — In physics, an ultraviolet divergence is a situation in which an integral, for example a Feynman diagram, diverges because of contributions of objects with very high energy (approaching infinity), or, equivalently, because of physical phenomena… … Wikipedia
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… … Wikipedia

QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… … Wikipedia

Functional integration — You may also be looking for functional integration (neurobiology) or functional integration (sociology). Functional integration is a collection of results in mathematics and physics where the domain of an integral is no longer a region of space,… … Wikipedia
BPST instanton — The BPST instanton is the instanton with winding number 1 found by Belavin, Polyakov, Schwartz and Tyupkin. It is a classical solution to the equations of motion in Euclidean space time (i.e. after Wick rotation), meaning it describes a… … Wikipedia
One-loop Feynman diagram — In physics, a one loop Feynman diagram is a connected Feynman diagram with only one cycle (unicyclic). Such a diagram can be obtained from a connected tree diagram by taking two external lines of the same type and joining them together into an… … Wikipedia
Soft-collinear effective theory — In quantum field theory, soft collinear effective theory (or SCET) is a theoretical framework for doing calculations in quantum chromodynamics (QCD) that involve interacting particles carrying widely different energies.The motivation for… … Wikipedia
