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
We expand the step-transition operator of any linear multi-step method with order s ≥ 2 up to O(τs+5). And through examples we show how much the perturbation
This paper deals with analytic and numerical dissipativity and exponential stability of singularly perturbed delay differential equations with any bounded state
