Convergence Space
In mathematics, a convergence space, also called a generalized convergence, is a set together with a relation called a that satisfies certain properties relating elements of ''X'' with the Family of sets, family of Filter (set theory), filters on ''X''. Convergence spaces generalize the notions of Filters in topology, convergence that are found in point-set topology, including Metric space, metric convergence and uniform convergence. Every topological space gives rise to a canonical convergence but there are convergences, known as , that do not arise from any topological space. An example of convergence that is in general non-topological is almost everywhere convergence. Many topological properties have generalizations to convergence spaces. Besides its ability to describe notions of convergence that Topology (structure), topologies are unable to, the Category (mathematics), category of convergence spaces has an important categorical property that the category of topological spac ...

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is Cladogram#Homoplasies, homoplasy. The recurrent evolution of flight is a classic example, as flying pterygota, insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homology (biology), homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convergence (eye)
A vergence is the simultaneous movement of both eyes in opposite directions to obtain or maintain single binocular vision. When a creature with binocular vision looks at an object, the eyes must rotate around a vertical axis so that the projection of the image is in the centre of the retina in both eyes. To look at an object closer, the eyes rotate towards each other ( convergence), while for an object farther away, they rotate away from each other ( divergence). Exaggerated convergence is called ''cross eyed viewing'' (focusing on the nose, for example). When looking into the distance, the eyes diverge until parallel, effectively fixating on the same point at infinity (or very far away). Vergence movements are closely connected to accommodation of the eye. Under normal visual conditions, looking at an object at a different distance will automatically cause changes in both vergence and accommodation, sometimes known as the '' accommodation-convergence reflex''. When under no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convergence (SSL)
Convergence was a proposed strategy for replacing SSL certificate authorities, first put forth by Moxie Marlinspike in August 2011 while giving a talk titled "SSL and the Future of Authenticity" at the Black Hat security conference. It was demonstrated with a Firefox addon and a server-side notary daemon. In the talk, Marlinspike proposed that all of the current problems with the certificate authority (CA) system could be reduced to a single missing property, which he called "trust agility" and which Convergence aimed to provide. The strategy claimed to be agile, secure, and distributed. As of 2013, Marlinspike was focused on an IETF proposal called TACK, which was designed to be an uncontroversial first step that advocates for dynamic certificate pinning instead of full CA replacement and reduces the number of times a third party needs to be trusted. Development of Convergence was continued in a "Convergence Extra" fork until about 2014. Background Convergence was based o ...

Convergent Series
In mathematics, a series is the sum of the terms of an infinite sequence of numbers. More precisely, an infinite sequence (a_1, a_2, a_3, \ldots) defines a series that is denoted :S=a_1 + a_2 + a_3 + \cdots=\sum_^\infty a_k. The th partial sum is the sum of the first terms of the sequence; that is, :S_n = a_1 +a_2 + \cdots + a_n = \sum_^n a_k. A series is convergent (or converges) if and only if the sequence (S_1, S_2, S_3, \dots) of its partial sums tends to a limit; that means that, when adding one a_k after the other ''in the order given by the indices'', one gets partial sums that become closer and closer to a given number. More precisely, a series converges, if and only if there exists a number \ell such that for every arbitrarily small positive number \varepsilon, there is a (sufficiently large) integer N such that for all n \ge N, :\left , S_n - \ell \right , 1 produce a convergent series: *: ++++++\cdots = . * Alternating the signs of reciprocals of powers o ...

Convergence (comics)
"Convergence" is a comic book storyline published by DC Comics that ran from April to May 2015. The series consists of an eponymous #0 issue, an eight-issue core miniseries, and 40 two-issue tie-in miniseries. "Convergence" continues from the weekly series ''Earth 2: World's End'' and ''The New 52: Futures End''. In the story, Brainiac (character), Brainiac collects cities and inhabitants from various timelines that have ended and traps them in domes on a planet outside of time and space. He then exposes the domes to one another to see how the characters interact. This event marks the return of DC characters and timelines from before the 2011 "Flashpoint (comics), Flashpoint" storyline that led to the creation of The New 52 Universe. Publication history In 2014, DC Comics announced the ''Convergence'' miniseries as a conclusion to ''The New 52: Futures End'' and ''Earth 2: World's End''. The miniseries was stated to involve characters from the pre-"Flashpoint (comics), Flashp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convergence (routing)
Convergence is the state of a set of routers that have the same topological information about the internetwork in which they operate. For a set of routers to have ''converged'', they must have collected all available topology information from each other via the implemented routing protocol, the information they gathered must not contradict any other router's topology information in the set, and it must reflect the real state of the network. In other words: in a converged network all routers "agree" on what the network topology looks like. Convergence is an important notion for a set of routers that engage in dynamic routing. All interior gateway protocols rely on convergence to function properly. "To have, or be, converged" is the normal state of an operational autonomous system. The Exterior Gateway Routing Protocol BGP typically never converges because the Internet is too big for changes to be communicated fast enough. Convergence process When a routing protocol proce ...
