  2. List of electronic color code mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_electronic_color...

    List of electronic color code mnemonics Mnemonics are used to help memorize the electronic color codes for resistors. Mnemonics describing specific and relatable scenarios are more memorable than abstract phrases.

  3. Electronic color code - Wikipedia

    en.wikipedia.org/wiki/Electronic_color_code

    An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as ...

  4. Mathematical formulation of the Standard Model - Wikipedia

    en.wikipedia.org/wiki/Mathematical_formulation...

    Mathematical formulation of the Standard Model Standard Model of Particle Physics. The diagram shows the elementary particles of the Standard Model (the Higgs boson, the three generations of quarks and leptons, and the gauge bosons ), including their names, masses, spins, charges, chiralities, and interactions with the strong, weak and electromagnetic forces. It also depicts the crucial role ...

  5. Lie algebra - Wikipedia

    en.wikipedia.org/wiki/Lie_algebra

    In mathematics, a Lie algebra (pronounced / liː / LEE) is a vector space together with an operation called the Lie bracket, an alternating bilinear map , that satisfies the Jacobi identity. In other words, a Lie algebra is an algebra over a field for which the multiplication operation (called the Lie bracket) is alternating and satisfies the ...

  6. Lie bracket of vector fields - Wikipedia

    en.wikipedia.org/wiki/Lie_bracket_of_vector_fields

    The Lie bracket is an R - bilinear operation and turns the set of all smooth vector fields on the manifold M into an (infinite-dimensional) Lie algebra . The Lie bracket plays an important role in differential geometry and differential topology, for instance in the Frobenius integrability theorem, and is also fundamental in the geometric theory ...

  7. Root system - Wikipedia

    en.wikipedia.org/wiki/Root_system

    In mathematics, a root system is a configuration of vectors in a Euclidean space satisfying certain geometrical properties. The concept is fundamental in the theory of Lie groups and Lie algebras, especially the classification and representation theory of semisimple Lie algebras. Since Lie groups (and some analogues such as algebraic groups) and Lie algebras have become important in many parts ...

  8. Lie–Kolchin theorem - Wikipedia

    en.wikipedia.org/wiki/Lie–Kolchin_theorem

    In mathematics, the Lie–Kolchin theorem is a theorem in the representation theory of linear algebraic groups; Lie's theorem is the analog for linear Lie algebras . It states that if G is a connected and solvable linear algebraic group defined over an algebraically closed field and. a representation on a nonzero finite-dimensional vector space ...
