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

1. Analysis of the finite element method for transmission/mixed boundary value problems on general polygonal domains, Hengguang Li, Anna L. Mazzucato, and Victor Nistor, 2010.
2. Improving the rate of convergence of high-order finite elements on polyhedra. II. Mesh refinements and interpolation,  Constantin Băcuță, Victor Nistor, and Ludmil Zikatanov, 2007.
3. Improving the rate of convergence of `high order finite elements’ on polygons and domains with cusps, Constantin Băcuță, Victor Nistor, and Ludmil Zikatanov, 2005.
