In polynomial optimization, two different and dual approaches are considered: the approximation of positive polynomials using sums of squares (SoS), that translates into Lasserre's SoS hierarchy, and the approximation of measures using truncated positive linear functionals (or truncated pseudo-moment sequences), that translates into Lasserre's moment hierarchy. In this thesis, we investigate exact and approximate representation properties in both the two cases. The representation of positive polynomials in terms of sums of squares is a central question in real algebraic geometry, that is answered by the Positivstellensätze. In particular, we investigate effective version of Putinar's Positivstellensatz, and provide new bounds on the degree ...
