  2. Harmonic progression (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Harmonic_progression...

    In mathematics, a harmonic progression (or harmonic sequence) is a progression formed by taking the reciprocals of an arithmetic progression, which is also known as an arithmetic sequence. Equivalently, a sequence is a harmonic progression when each term is the harmonic mean of the neighboring terms.

  3. Harmonic series (mathematics) - Wikipedia

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

    [1] [2] Every term of the harmonic series after the first is the harmonic mean of the neighboring terms, so the terms form a harmonic progression; the phrases harmonic mean and harmonic progression likewise derive from music. [2] Beyond music, harmonic sequences have also had a certain popularity with architects.

  4. Harmonic number - Wikipedia

    The harmonic number with = ⌊ ⌋ (red line) with its asymptotic limit + ⁡ (blue line) where is the Euler–Mascheroni constant.. In mathematics, the n-th harmonic number is the sum of the reciprocals of the first n natural numbers: [1] = + + + + = =.

    In mathematics, the QM-AM-GM-HM inequalities, also known as the mean inequality chain, state the relationship between the harmonic mean, geometric mean, arithmetic mean, and quadratic mean (also known as root mean square). Suppose that ,, …, are positive real numbers. Then

    Every n in M x can be written as n = m 2 r with positive integers m and r, where r is square-free. Since only the k primes p 1, ..., p k can show up (with exponent 1) in the prime factorization of r, there are at most 2 k different possibilities for r. Furthermore, there are at most √ x possible values for m.

  8. Sequence - Wikipedia

    en.wikipedia.org/wiki/Sequence

    If A is a set, the free monoid over A (denoted A *, also called Kleene star of A) is a monoid containing all the finite sequences (or strings) of zero or more elements of A, with the binary operation of concatenation. The free semigroup A + is the subsemigroup of A * containing all elements except the empty sequence.

    The Romanesca originated from the 16th and 17th centuries as a common musical backdrop in a minor key for singing poetry as well as the basis for variations over a repeating harmonic progression. [4] The later Romanesca is a similar progression and features three variants: the leaping variant, the stepwise variant, and the galant variant, a ...
