Maximum Norm Error Estimates for Quadratic Block Finite Elements with Twenty-Six Degrees of Freedom
For a model elliptic boundary value problem in three dimensions, we give the weak estimates for the quadratic block finite element with twenty-six degrees of freedom (QBFETSDF). Combined with the estimates for discrete Green’s function, we get maximum norm error estimates for the QBFETSDF.
