Convergence Definition from Business & Finance Dictionaries & Glossaries
Campbell R. Harvey's Hypertextual Finance Glossary
The movement of the price of a futures contract toward the price of the underlying cash commodity. At the start, the contract price is higher because of time value. But as the contract nears expiration, and time value decreases, the futures price and the cash price converge.

The coming together of futures prices and cash market prices on the last trading day of a futures contract.

Literally, coming to a point with time. The values in the sequence 1, 1/2, 1/3, 1/4,... converge to zero whereas the values in the sequence 0/1, 1/2, 2/3, 3/4, ... converge to one. Convergence requires that the differences between neighboring values decrease. If they do not, they may tend to infinity as in 1, 2, 3,... or end up oscillating as in ... +1, -1, +1, -1,... The convergence model of communication postulates that as people communicate with each other they become more similar in knowledge and in attitudes and thus converge to form a homogeneous distribution. (Krippendorff )
Wind movement that results in a horizontal net inflow of air into a particular region. Convergent winds at lower levels are associated with upward motion. Contrast with divergence.
A contraction of a vector field; the opposite of divergence . Convergence in a horizontal wind field indicates that more air is entering a given area than is leaving at that level. To compensate for the resulting "excess," vertical motion may result: upward forcing if convergence is at low levels, or downward forcing (subsidence ) if convergence is at high levels. Upward forcing from low-level convergence increases the potential for thunderstorm development (when other factors, such as instability , are favorable). Compare with confluence .
Convergence Definition from Computer & Internet Dictionaries & Glossaries
Internet Glossary
(1) The coming together of two or more disparate disciplines or technologies. For example, the so-called fax revolution was produced by a convergence of telecommunications technology, optical scanning technology, and printing technology.

(2) In graphics, convergence refers to how sharply an individual color pixel on a monitor appears. Each pixel is composed of three dots -- a red, blue, and green one. If the dots are badly misconverged, the pixel will appear blurry. All monitors have some convergence errors, but they differ in degree.

Television and Video Glossary
The correct aiming of the three electron beams in a direct viewed picture tube or three separate pictures from tubes in a projection TV (for red, blue, and green) to be together at all times. Without proper convergence, objects on the screen will have colored halos around them, white lines will seem to have a red, green, or blue line next to them, and resolution will be poorer. The most common reason for misconvergence is the coils attached to the neck of the picture tube not in the proper position which usually takes a time consuming trial and error process to correct. Often perfect convergence cannot be achieved over the entire screen so a compromise where the errors are minimized but not completely eliminated must be accepted. It may be noted that a convergence error of one fifth of one percent means that one of the electron beams is off by a scan line causing a halving of the resolution at that spot on the screen. Also "convergence" refers to the bringing together and integrating of two or more systems or technologies so that components can be shared. An example is the development and manufacturing of video monitors suitable for television, movies, entertainment, and also computers and data display.

Three colors-red, blue, and green-are used in television to produce all colors. These separate scanning beams (one for each color) must strike their targeted phosphors (screen's internal coating) with precise accuracy. If the beams are out of alignment, then the image and colors appear muddied.
