  2. Convergent thinking - Wikipedia

    en.wikipedia.org/wiki/Convergent_thinking

    Convergent thinking is the type of thinking that focuses on coming up with the single, well-established answer to a problem. [1] It is oriented toward deriving the single best, or most often correct answer to a question. Convergent thinking emphasizes speed, accuracy, and logic and focuses on recognizing the familiar, reapplying techniques, and ...

  3. Filter (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Filter_(mathematics)

    Since the latter cannot be extended further, ↑ {1} is an ultrafilter. In mathematics, a filter or order filter is a special subset of a partially ordered set (poset), describing "large" or "eventual" elements. Filters appear in order and lattice theory, but also topology, whence they originate. The notion dual to a filter is an order ideal .

  4. Convergent validity - Wikipedia

    en.wikipedia.org/wiki/Convergent_validity

    Convergent validity, along with discriminant validity, is a subtype of construct validity. Convergent validity can be established if two similar constructs correspond with one another, while discriminant validity applies to two dissimilar constructs that are easily differentiated. Campbell and Fiske (1959) developed the Multitrait-Multimethod ...

  6. Convergent evolution - Wikipedia

    en.wikipedia.org/wiki/Convergent_evolution

    e. 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 homoplasy.

  7. List of examples of convergent evolution - Wikipedia

    Here is a list of examples in which unrelated proteins have similar functions with different structure. The convergent orientation of the catalytic triad in the active site of serine and cysteine proteases independently in over 20 enzyme superfamilies. [251] The use of an N-terminal threonine for proteolysis.

  8. Sequence - Wikipedia

    en.wikipedia.org/wiki/Sequence

    In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms ). The number of elements (possibly infinite) is called the length of the sequence. Unlike a set, the same elements can appear multiple times at different positions ...

  9. Convergent series - Wikipedia

    en.wikipedia.org/wiki/Convergent_series

    Convergent series. In mathematics, a series is the sum of the terms of an infinite sequence of numbers. More precisely, an infinite sequence defines a series S that is denoted. The n th partial sum Sn is the sum of the first n terms of the sequence; that is, A series is convergent (or converges) if and only if the sequence of its partial sums ...
