Normalized B-spline-like representation for low-degree Hermite osculatory interpolation problems
M. Boushabi, S. Eddargani, M. J. Ibáñez +1
This paper deals with Hermite osculatory interpolating splines. For a partition of a real interval endowed with a refinement consisting in dividing each subinterval into two small…

Near-best univariate spline discrete quasi-interpolants on non-uniform partitions
D. Barrera, M. J. Ibanez, Paul Sablonniere +1
Univariate spline discrete quasi-interpolants (abbr. dQIs) are approximation operators using B-spline expansions with coefficients which are linear combinations of discrete values…
