Talk:Galerkin method

From Wikipedia, the free encyclopedia

as i understand it, galerkin method is not specific to differential formulations but in general applied to operation equation. for example Lu=f, then you expand u in a basis v_i and do (v_i,Lv_j)=(v_i,f). for differential formulations, you can use identities to get the LHS to be more convient. however if you have an integral equation then you have two sets of integrals. if no one objects, i will modify the article in this generality.
