  2. Elliptic curve point multiplication - Wikipedia

    en.wikipedia.org/wiki/Elliptic_curve_point...

    Given a curve, E, defined by some equation in a finite field (such as E: y 2 = x 3 + ax + b), point multiplication is defined as the repeated addition of a point along that curve. Denote as nP = P + P + P + … + P for some scalar (integer) n and a point P = (x, y) that lies on the curve, E. This type of curve is known as a Weierstrass curve.

  3. Complex multiplication - Wikipedia

    en.wikipedia.org/wiki/Complex_multiplication

    In mathematics, complex multiplication (CM) is the theory of elliptic curves E that have an endomorphism ring larger than the integers. [1] Put another way, it contains the theory of elliptic functions with extra symmetries, such as are visible when the period lattice is the Gaussian integer lattice or Eisenstein integer lattice.

  4. Convolution theorem - Wikipedia

    en.wikipedia.org/wiki/Convolution_theorem

    Equivalently, if = {} is a smooth "slowly growing" ordinary function, it guarantees the existence of both, multiplication and convolution product. [ 7 ] [ 8 ] [ 9 ] In particular, every compactly supported tempered distribution, such as the Dirac delta , is "rapidly decreasing".

  5. Hadamard product (matrices) - Wikipedia

    en.wikipedia.org/wiki/Hadamard_product_(matrices)

    The Hadamard product operates on identically shaped matrices and produces a third matrix of the same dimensions. In mathematics, the Hadamard product (also known as the element-wise product, entrywise product [1]: ch. 5 or Schur product [2]) is a binary operation that takes in two matrices of the same dimensions and returns a matrix of the multiplied corresponding elements.

  6. Left and right (algebra) - Wikipedia

    en.wikipedia.org/wiki/Left_and_right_(algebra)

    If for some e, the left operation L e is the identity operation, then e is called a left identity. Similarly, if R e = id, then e is a right identity. In ring theory, a subring which is invariant under any left multiplication in a ring is called a left ideal. Similarly, a right multiplication-invariant subring is a right ideal.

  7. Cross-multiplication - Wikipedia

    en.wikipedia.org/wiki/Cross-multiplication

    The rule of three [1] was a historical shorthand version for a particular form of cross-multiplication that could be taught to students by rote. It was considered the height of Colonial maths education [2] and still figures in the French national curriculum for secondary education, [3] and in the primary education curriculum of Spain. [4]

  8. Six factor formula - Wikipedia

    en.wikipedia.org/wiki/Six_factor_formula

    The multiplication factor, k, is defined as (see nuclear chain reaction): k = ⁠ number of neutrons in one generation / number of neutrons in preceding generation ⁠. If k is greater than 1, the chain reaction is supercritical, and the neutron population will grow exponentially.

  9. Multilinear polynomial - Wikipedia

    en.wikipedia.org/wiki/Multilinear_polynomial

    In algebra, a multilinear polynomial [1] is a multivariate polynomial that is linear (meaning affine) in each of its variables separately, but not necessarily simultaneously. ...
