Abstract:It is a fundamental topic and of both theoretical and practical meanings to construct optimal schemes, especially ones of low degrees. In this talk, some low-degree optimal finite element schemes are presented for second/fourth order elliptic problems on triangular/quadrilateral grids. Both source problems and eigenvalue problems are discussed, and some interesting phenomena are introduced beside the construction and analysis of the methods
