A robust approach for performing weighted minimax polynomial approximation
Salle Lagrange gris, March 31, 2016 at 2:00 PM
Minimax polynomial approximation problems are well known to people implementing mathematical libraries, but also in Signal Processing, for digital filter design. In this talk, I will discuss the main issues that are attributed to such problems in practice. To solve them in a robust way, we will need the help of several branches of mathematics, from Approximation Theory and Numerical Analysis, to Potential Theory and Algorithmic Number Theory.
