Polynomial approximation from diffused data: unisolvence and stability
Ludovico Bruni Bruno, Stefano De Marchi, Giacomo Elefante
In this work, we address the problem of polynomial interpolation of non-pointwise data. More specifically, we assume that our input information comes from measurements obtained on…

Bivariate polynomial histopolation techniques on Padua, Fekete and Leja triangles
Ludovico Bruni Bruno, Francesco Dell'Accio, Wolfgang Erb +1
This paper explores the reconstruction of a real-valued function defined over a domain using bivariate polynomials that satisfy triangular histopolatio…

Polynomial histopolation on mock-Chebyshev segments
Ludovico Bruni Bruno, Francesco Dell'Accio, Wolfgang Erb +1
In computational practice, we often encounter situations where only measurements at equally spaced points are available. Using standard polynomial interpolation in such cases can l…
