It is given that the conditions which guarantee that a given BVP can be reformulated in variational form. It is also shown that by applying the Lax-milgram theorem the existence and uniqueness of solution for the variational problem is proved.enVariational MethodsSolutions of LinearBoundaryvalueProblemsThesis
