We propose the use of an averaging scheme, which recovers gradients from piecewise linear finite element approximations on the (1 + α)-regular triangular elements to gradients of the weak solution of a secondorder elliptic boundary value problem in the 2-dimensional space. The recovered gradients, f

Piecewise linear finite element approximations to two-dimensional Poisson problems are treated. For simplicity, consideration is restricted to problems having Dirichlet boundary conditions and defined on rectangular domains R which are partitioned by a uniform triangular mesh. It is also required th
