  2. Alternating series - Wikipedia

    en.wikipedia.org/wiki/Alternating_series

    But the Riemann series theorem states that conditionally convergent series can be rearranged to create arbitrary convergence. [4] The general principle is that addition of infinite sums is only commutative for absolutely convergent series. For example, one false proof that 1=0 exploits the failure of associativity for infinite sums.

  3. Abel's test - Wikipedia

    en.wikipedia.org/wiki/Abel's_test

    Abel's uniform convergence test is a criterion for the uniform convergence of a series of functions or an improper integration of functions dependent on parameters. It is related to Abel's test for the convergence of an ordinary series of real numbers, and the proof relies on the same technique of summation by parts. The test is as follows.

    Dissociative identity disorder [1] [2]; Other names: Multiple personality disorder Split personality disorder: Specialty: Psychiatry, clinical psychology: Symptoms: At least two distinct and relatively enduring personality states, [3] recurrent episodes of dissociative amnesia, [3] inexplicable intrusions into consciousness (e.g., voices, intrusive thoughts, impulses, trauma-related beliefs ...

    The PLATO system was launched in 1960 at the University of Illinois and subsequently commercially marketed by Control Data Corporation.It offered early forms of social media features with innovations such as Notes, PLATO's message-forum application; TERM-talk, its instant-messaging feature; Talkomatic, perhaps the first online chat room; News Report, a crowdsourced online newspaper, and blog ...

  6. Weierstrass M-test - Wikipedia

    en.wikipedia.org/wiki/Weierstrass_M-test

    In mathematics, the Weierstrass M-test is a test for determining whether an infinite series of functions converges uniformly and absolutely. It applies to series whose terms are bounded functions with real or complex values, and is analogous to the comparison test for determining the convergence of series of real or complex numbers.

  7. Bayesian inference - Wikipedia

    en.wikipedia.org/wiki/Bayesian_inference

    Bayesian inference (/ ˈ b eɪ z i ə n / BAY-zee-ən or / ˈ b eɪ ʒ ən / BAY-zhən) [1] is a method of statistical inference in which Bayes' theorem is used to update the probability for a hypothesis as more evidence or information becomes available.

  8. Network convergence - Wikipedia

    en.wikipedia.org/wiki/Network_convergence

    In the convergent network, different forms of information can be re-engineered to provide better, more flexible service to the user. For example, telephone networks can transmit data and video and cable networks are able to provide voice services. The reason media convergence occurs is due to both corporation and consumer developments.

  9. Ratio test - Wikipedia

    en.wikipedia.org/wiki/Ratio_test

    In mathematics, the ratio test is a test (or "criterion") for the convergence of a series =, where each term is a real or complex number and a n is nonzero when n is large. The test was first published by Jean le Rond d'Alembert and is sometimes known as d'Alembert's ratio test or as the Cauchy ratio test.
