In this paper,we discuss an inverse eigenvalue problem for constructing a 2n×2n Jacobi matrix T such that its 2n eigenvalues are given distinct real values and
The main aim of this paper is to study the superconvergence accuracy analysis of the famous ACM’s nonconforming finite element for biharmonic equation under an
Superconvergence structures for rectangular and triangular finite elements are summarized. Two debatable issues in Zhu’s paper [18] are discussed. A superclose
