  2. Mathematical formulation of the Standard Model - Wikipedia

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

    This article describes the mathematics of the Standard Model of particle physics, a gauge quantum field theory containing the internal symmetries of the unitary product group SU(3) × SU(2) × U(1). The theory is commonly viewed as describing the fundamental set of particles – the leptons, quarks, gauge bosons and the Higgs boson.

  3. Quantum logic - Wikipedia

    en.wikipedia.org/wiki/Quantum_logic

    The most notable difference between quantum logic and classical logic is the failure of the propositional distributive law: [1]. p and (q or r) = (p and q) or (p and r),. where the symbols p, q and r are propositional variables.

  4. Regge calculus - Wikipedia

    en.wikipedia.org/wiki/Regge_calculus

    The starting point for Regge's work is the fact that every four dimensional time orientable Lorentzian manifold admits a triangulation into simplices.Furthermore, the spacetime curvature can be expressed in terms of deficit angles associated with 2-faces where arrangements of 4-simplices meet.

  5. Mathematical Foundations of Quantum Mechanics - Wikipedia

    en.wikipedia.org/wiki/Mathematical_Foundations...

    It was considered the most complete book written in quantum mechanics at the time of release. [2] [14] It was praised for its axiomatic approach. [2] A review by Jacob Tamarkin compared von Neumann's book to what the works on Niels Henrik Abel or Augustin-Louis Cauchy did for mathematical analysis in the 19th century, but for quantum mechanics ...

  6. Mathematical formulation of quantum mechanics - Wikipedia

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

    The first complete mathematical formulation of this approach, known as the Dirac–von Neumann axioms, is generally credited to John von Neumann's 1932 book Mathematical Foundations of Quantum Mechanics, although Hermann Weyl had already referred to Hilbert spaces (which he called unitary spaces) in his 1927 classic paper and book.

  7. Exact solutions in general relativity - Wikipedia

    en.wikipedia.org/wiki/Exact_solutions_in_general...

    In general relativity, an exact solution is a (typically closed form) solution of the Einstein field equations whose derivation does not invoke simplifying approximations of the equations, though the starting point for that derivation may be an idealized case like a perfectly spherical shape of matter.

  8. Eric Lerner - Wikipedia

    en.wikipedia.org/wiki/Eric_Lerner

    Eric J. Lerner (born May 31, 1947) is an American popular science writer and independent plasma researcher. [2] He wrote the 1991 book The Big Bang Never Happened, which advocates Hannes Alfvén's plasma cosmology instead of the Big Bang theory.

  9. Linear programming - Wikipedia

    en.wikipedia.org/wiki/Linear_programming

    Linear programming (LP), also called linear optimization, is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements and objective are represented by linear relationships. Linear programming is a special case of mathematical programming (also known as mathematical optimization).
