abstract = {<p style="text-align: justify;">A basis for the quadratic ($P_2$) nonconforming element of
Fortin and Soulie on triangles is introduced. The local and global
interpolation operators are defined. Error estimates of optimal order
are derived in both broken energy and $L^2(\Omega)$-norms for second-order
elliptic problems. Brief numerical results are also shown.</p>},
