I include here the selected papers that contain results on Numerical Methods, even if they contain also results on PDEs.

1. Constantin Bacuta, Victor Nistor, and Ludmil Zikatanov, Improving the rate of convergence of high-order finite elements on polyhedra. II: mesh refinements and interpolation, Numer. Funct. Anal. Optim. 28, No. 7–8, 775–824 (2007; Zbl 1122.65109)
