| Abstract: | For Poisson boundary value problems in three dimensions,using the formulae of integration by parts of multiple integral,and combined with the conclusions of the discrete Green’s function and Green’s function and the properties of finite element and the proof techniques,a result of weak correction estimate for the block finite element of degree m is given under a uniform subdivision,which provides a train of thought for the study of multi-dimensional higher-order projection interpolation correction. |
