Local approximation from spline spaces on box meshes
A. Bressan and T. Lyche
This paper analyzes the approximation properties of spaces of piecewise tensor product polynomials over box meshes with a focus on application to isogeometric analysis. Local and global error bounds w...

On best constants in L^2 approximation
A. Bressan, MS Floater, and E. Sande
In this paper we provide explicit upper and lower bounds on certain L-2 n-widths, i.e., best constants in L-2 approximation. We further describe a numerical method to compute these n-widths approximat...
