Galerkin Method


A method of determining coefficients alpha_k in a power series solution

 y(x)=y_0(x)+sum_(k=1)^nalpha_ky_k(x)

of the ordinary differential equation L^~[y(x)]=0 so that L^~[y(x)], the result of applying the ordinary differential operator to y(x), is orthogonal to every y_k(x) for k=1, ..., n (Itô 1980).

Galerkin methods are equally ubiquitous in the solution of partial differential equations, and in fact form the basis for the finite element method.
