Error analysis for quadratic spline quasi-interpolants on non-uniform criss-cross triangulations of bounded rectangular domains
Catterina Dagnino, Paul Sablonnière
Given a non-uniform criss-cross partition of a rectangular domain , we analyse the error between a function defined on and two types of -quadratic spline quasi-inte…

On two families of near-best spline quasi-interpolants on non-uniform partitions of the real line
Domingo Barrera, Maria José Ibañez Pérez, Paul Sablonnière +1
The univariate spline quasi-interpolants (abbr. QIs) studied in this paper are approximation operators using B-spline expansions with coefficients which are linear combinations of…
