Galerkin equation
http://fischerp.cs.illinois.edu/tam470/refs/galerkin2.pdf The analysis of these methods proceeds in two steps. First, we will show that the Galerkin equation is a well-posed problem in the sense of Hadamard and therefore admits a unique solution. In the second step, we study the quality of approximation of the Galerkin solution . See more In mathematics, in the area of numerical analysis, Galerkin methods are named after the Soviet mathematician Boris Galerkin. They convert a continuous operator problem, such as a differential equation, … See more Here, we will restrict ourselves to symmetric bilinear forms, that is $${\displaystyle a(u,v)=a(v,u).}$$ While this is not really a restriction of Galerkin methods, … See more The approach is usually credited to Boris Galerkin. The method was explained to the Western reader by Hencky and Duncan among others. Its convergence was studied by … See more We first introduce and illustrate the Galerkin method as being applied to a system of linear equations See more Weak formulation of a linear equation Let us introduce Galerkin's method with an abstract problem posed as a weak formulation on a Hilbert space $${\displaystyle V}$$, … See more I.
