摘要：
It is proved that under certain assumptions on the functions q(t) and f(t), there is one and only one function u0(t) {W21 o (a,b) at which the functional ∫ ab [u(t)2 dt + ∫ ab q(t)u2 (t)dt} - 2∫ ab {f(t)u(t)dt attains its minimum. An error bound for the finite element method for computing the function u0(t) in terms of q(t), f(t), and the meshsize h is presented.
