  2. Multiset - Wikipedia

    en.wikipedia.org/wiki/Multiset

    A related example is the multiset of solutions of an algebraic equation. A quadratic equation, for example, has two solutions. However, in some cases they are both the same number. Thus the multiset of solutions of the equation could be {3, 5}, or it could be {4, 4}. In the latter case it has a solution of multiplicity 2.

  3. Representation theory of the Lorentz group - Wikipedia

    en.wikipedia.org/wiki/Representation_theory_of...

    So for example, the (⁠ 1 / 2 ⁠, ⁠ 1 / 2 ⁠) representation has spin 1 and spin 0 subspaces of dimension 3 and 1 respectively. Since the angular momentum operator is given by J = A + B , the highest spin in quantum mechanics of the rotation sub-representation will be ( m + n )ℏ and the "usual" rules of addition of angular momenta and ...

    Singh cites Pingala's cryptic formula misrau cha ("the two are mixed") and scholars who interpret it in context as saying that the number of patterns for m beats (F m+1) is obtained by adding one [S] to the F m cases and one [L] to the F m−1 cases. [12] Bharata Muni also expresses knowledge of the sequence in the Natya Shastra (c. 100 BC–c ...

    en.wikipedia.org/wiki/History_of_algebra

    Later, René Descartes (17th century) introduced the modern notation (for example, the use of x—see below) and showed that the problems occurring in geometry can be expressed and solved in terms of algebra (Cartesian geometry). Equally important as the use or lack of symbolism in algebra was the degree of the equations that were addressed.

  6. Matrix (mathematics) - Wikipedia

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

    Familiar properties of numbers extend to these operations on matrices: for example, addition is commutative, that is, the matrix sum does not depend on the order of the summands: A + B = B + A. [9] The transpose is compatible with addition and scalar multiplication, as expressed by ( c A ) T = c ( A T ) and ( A + B ) T = A T + B T .

    Water is an inorganic compound with the chemical formula H 2 O.It is a transparent, tasteless, odorless, [c] and nearly colorless chemical substance.It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent [20]).

    [54] [55] Also in 2021, TeamViewer entered a partnership with the Mercedes-AMG Petronas Formula One Team and the Mercedes-EQ Formula E Team, who will use the company's branding on cars and drivers' racing suits. [56] The latter ended when the Mercedes team withdrew from Formula E after the 2022 season. [57]
