内容概要

　　This book cove the advanced study on the global
superconvegence of elliptic equatio in both theory and computation,
where the main materials are adapted from our journal pape
published. A deep and rather completed analysis of global
supperconvergence is explored for bilinear, biquadratic, Adini's
and bi-cubic Hermite elements, as well as for the finite difference
method. Poisson's and the biharmonic equatio are included, and
eigenvalue and semi-linear problems are discussed. The singularity
problems, blending problems, coupling techniques, a posteriori
interpolant techniques, and some physical and engineering problems
are studied. Numerical examples are provided for verification of
the analysis, and other numerical experiments can be found from our
publicatio. This book has also summarized some important results of
Lin, his colleagues and othe. This book is written for researche
and graduate students of mathematics and engineering to study and
apply the global superconvergence for numerical PDE.
