  2. Weak formulation - Wikipedia

    en.wikipedia.org/wiki/Weak_formulation

    This is a formulation of the Lax–Milgram theorem which relies on properties of the symmetric part of the bilinear form. It is not the most general form. It is not the most general form. Let V {\displaystyle V} be a real Hilbert space and a ( ⋅ , ⋅ ) {\displaystyle a(\cdot ,\cdot )} a bilinear form on V {\displaystyle V} , which is

    en.wikipedia.org/wiki/Small-world_experiment

    The small-world experiment comprised several experiments conducted by Stanley Milgram and other researchers examining the average path length for social networks of people in the United States. [1] The research was groundbreaking in that it suggested that human society is a small-world -type network characterized by short path-lengths.

  4. Babuška–Lax–Milgram theorem - Wikipedia

    en.wikipedia.org/wiki/Babuška–Lax–Milgram...

    The achievement of Lax and Milgram in their 1954 result was to specify sufficient conditions for this weak formulation to have a unique solution that depends continuously upon the specified datum f ∈ V ∗: it suffices that U = V is a Hilbert space, that B is continuous, and that B is strongly coercive, i.e.

    en.wikipedia.org/wiki/Galerkin_method

    Ritz–Galerkin method (after Walther Ritz) typically assumes symmetric and positive definite bilinear form in the weak formulation, where the differential equation for a physical system can be formulated via minimization of a quadratic function representing the system energy and the approximate solution is a linear combination of the given set ...

  8. Weak solution - Wikipedia

    en.wikipedia.org/wiki/Weak_solution

    In mathematics, a weak solution (also called a generalized solution) to an ordinary or partial differential equation is a function for which the derivatives may not all exist but which is nonetheless deemed to satisfy the equation in some precisely defined sense. There are many different definitions of weak solution, appropriate for different ...

  9. Six degrees of separation - Wikipedia

    en.wikipedia.org/wiki/Six_degrees_of_separation

    Milgram's article made famous [9] his 1967 set of experiments to investigate de Sola Pool and Kochen's "small world problem." Mathematician Benoit Mandelbrot , born in Warsaw, growing up in Poland then France, was aware of the Statist rule of thumb , and was also a colleague of de Sola Pool, Kochen and Milgram at the University of Paris during ...
