Sums of Squares: from Algebra to Analysis

Start: 17/01/2024, 3:00
Location: B91.100

The representation of non-negative functions as sums of squares has become an important tool in many modeling and optimization tasks. Traditionally applied to polynomial functions, it requires rich tools from algebraic geometry that led to many developments in the last twenty years. In this lecture, I will look at this problem from a functional analysis point of view, leading to new applications and new results on the performance of sum-of-squares optimization.

This presentation is given in the framework of ERC project "Spikycontrol"
