  2. List of mathematical series - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_series

    An infinite series of any rational function of can be reduced to a finite series of polygamma functions, by use of partial fraction decomposition, [8] as explained here. This fact can also be applied to finite series of rational functions, allowing the result to be computed in constant time even when the series contains a large number of terms.

    en.wikipedia.org/wiki/PDF

    The file starts with a header containing a magic number (as a readable string) and the version of the format, for example %PDF-1.7. The format is a subset of a COS ("Carousel" Object Structure) format. [24] A COS tree file consists primarily of objects, of which there are nine types: [17] Boolean values, representing true or false; Real numbers ...

    A number that has the same number of digits as the number of digits in its prime factorization, including exponents but excluding exponents equal to 1. A046758: Extravagant numbers: 4, 6, 8, 9, 12, 18, 20, 22, 24, 26, 28, 30, 33, 34, 36, 38, ... A number that has fewer digits than the number of digits in its prime factorization (including ...

    C 1 (q) also exists, but is the same as A 1 (q). C 2 (q) also exists, but is the same as B 2 (q). This is the group obtained from the split orthogonal group in dimension 2n by taking the kernel of the determinant (or Dickson invariant in characteristic 2) and spinor norm maps and then killing the center.

    It is an example of a 2-regular sequence. [ 2 ] Asymptotically , the value of the n {\displaystyle n} th sorting number fluctuates between approximately n log 2 ⁡ n − n {\displaystyle n\log _{2}n-n} and n log 2 ⁡ n − 0.915 n , {\displaystyle n\log _{2}n-0.915n,} depending on the ratio between n {\displaystyle n} and the nearest power of ...

    en.wikipedia.org/wiki/X86_instruction_listings

    This is done by defining a series of state-components, each with a size and offset within a given save area, and each corresponding to a subset of the state needed for one CPU extension or another. The EAX=0Dh CPUID leaf is used to provide information about which state-components the CPU supports and what their sizes/offsets are, so that the OS ...

  8. Fibonacci search technique - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_search_technique

    Let k be defined as an element in F, the array of Fibonacci numbers. n = F m is the array size. If n is not a Fibonacci number, let F m be the smallest number in F that is greater than n. The array of Fibonacci numbers is defined where F k+2 = F k+1 + F k, when k ≥ 0, F 1 = 1, and F 0 = 1. To test whether an item is in the list of ordered ...

  9. Arithmetical hierarchy - Wikipedia

    en.wikipedia.org/wiki/Arithmetical_hierarchy

    An illustration of how the levels of the hierarchy interact and where some basic set categories lie within it. In mathematical logic, the arithmetical hierarchy, arithmetic hierarchy or Kleene–Mostowski hierarchy (after mathematicians Stephen Cole Kleene and Andrzej Mostowski) classifies certain sets based on the complexity of formulas that define them.
