A gradient recovery operator based on an oblique projection
Electronic transactions on numerical analysis, Tome 37 (2010), pp. 166-172
We present a construction of a gradient recovery operator based on an oblique projection, where the basis functions of two involved spaces satisfy a condition of biorthogonality. The biorthogonality condition guarantees that the recovery operator is local.
