41Newman-Penrose formalism — The Newman Penrose Formalism is a set of notation developed by Ezra T. Newman and Roger Penrose [cite journal | author= Ezra T. Newman and Roger Penrose | title=An Approach to Gravitational Radiation by a Method of Spin Coefficients |… …
42McCarthy Formalism — In computer science and recursion theory the McCarthy Formalism (1963) of computer scientist John McCarthy clarifies the notion of recursive functions by use of the IF THEN ELSE construction common to computer science, together with the four of… …
43Scientific formalism — is a broad term for a family of approaches to the presentation of science. It is viewed as an important part of the scientific method, especially in the physical sciences.Levels of formalismThere are multiple levels of scientific formalism… …
44Parameterized post-Newtonian formalism — Post Newtonian formalism is a calculational tool that expresses Einstein s (nonlinear) equations of gravity in terms of the lowest order deviations from Newton s theory. This allows approximations to Einstein s equations to be made in the case of …
45Keldysh formalism — In condensed matter physics, the Keldysh formalism describes the evolution of quantum mechanical states in the presence of a time varying magnetic field. It is related to the non equilibrium Green s function.References [1] to [4] give the usage… …
46Batalin-Vilkovisky formalism — In theoretical physics, Batalin Vilkovisky (BV) formalism was developed as a method for determining the ghost structure for theories, such as gravity and supergravity, whose Hamiltonian formalism has constraints not related to a Lie algebra… …
47Tetrad formalism — The tetrad formalism is a transformed coordinate approach to General Relativity.In the tetrad formalism, a tetrad basis is chosen a set of four independent vector fields {e {(a)}^{mu}} {a=1dots4} that together span the 4D vector space at each… …
48BRST formalism — (A draft of an alternate exposition has been added at BRST quantization.)In theoretical physics, the BRST formalism is a method of implementing first class constraints. The letters BRST stand for Becchi, Rouet, Stora, and (independently) Tyutin… …
49GENERIC formalism — In non equilibrium thermodynamics, GENERIC is an acronym for General Equation for Non Equilibrium Reversible Irreversible Coupling. It is the general form of dynamic equation for a system with both reversible and irreversible dynamics (generated… …
50Ethical formalism — is a type of ethical theory which defines moral judgements in terms of their logical form (e.g., as laws or universal prescriptions ) rather than their content (e.g., as judgements about what actions will best promote human well being). The term… …
