Bernstein-type approximation of set-valued functions in the symmetric difference metric
Shay Kels, Nira Dyn
We study the approximation of univariate and multivariate set-valued functions (SVFs) by the adaptation to SVFs of positive samples-based approximation operators for real-valued fu…

Subdivision schemes of sets and the approximation of set-valued functions in the symmetric difference metric
Shay Kels, Nira Dyn
In this work we construct subdivision schemes refining general subsets of R^n and study their applications to the approximation of set-valued functions. Differently from previous w…
