  2. Matrix theory (physics) - Wikipedia

    en.wikipedia.org/wiki/Matrix_theory_(physics)

    The BFSS matrix model can therefore be used as a prototype for a correct formulation of M-theory and a tool for investigating the properties of M-theory in a relatively simple setting. The BFSS matrix model is also considered the worldvolume theory of a large number of D0-branes in Type IIA string theory. [2]

  3. M-theory - Wikipedia

    en.wikipedia.org/wiki/M-theory

    In physics, a matrix model is a particular kind of physical theory whose mathematical formulation involves the notion of a matrix in an important way. A matrix model describes the behavior of a set of matrices within the framework of quantum mechanics. [43] [44] One important [why?] example of a matrix model is the BFSS matrix model proposed by ...

    en.wikipedia.org/wiki/Matrix_string_theory

    In physics, matrix string theory is a set of equations that describe superstring theory in a non-perturbative framework. Type IIA string theory can be shown to be equivalent to a maximally supersymmetric two-dimensional gauge theory , the gauge group of which is U( N ) for a large value of N .

    en.wikipedia.org/wiki/Nathan_Seiberg

    As part of his work on the BFSS matrix model, Seiberg discovered little string theories. [21] These are limits of string theory without gravity that are not local quantum field theories.

  7. Tom Banks (physicist) - Wikipedia

    en.wikipedia.org/wiki/Tom_Banks_(physicist)

    Along with Willy Fischler, Stephen Shenker, and Leonard Susskind, he is one of the four originators of M(atrix) theory, or BFSS Matrix Theory, an attempt to formulate M theory in a nonperturbative manner.

  8. Basic feasible solution - Wikipedia

    en.wikipedia.org/wiki/Basic_feasible_solution

    In the theory of linear programming, a basic feasible solution (BFS) is a solution with a minimal set of non-zero variables.Geometrically, each BFS corresponds to a vertex of the polyhedron of feasible solutions.

  9. Background field method - Wikipedia

    en.wikipedia.org/wiki/Background_field_method

    In theoretical physics, background field method is a useful procedure to calculate the effective action of a quantum field theory by expanding a quantum field around a classical "background" value B:
