Making Non-Negative Polynomials into Sums of Squares

Philipp J. di Dio

We study linear operators $T : R [x_{1}, \dots, x_{n}] \to R [x_{1}, \dots, x_{n}]$ , especially for the purpose to move sets $S \subseteq R [x_{1}, \dots, x_{n}]$ into cones $C\sub…

On Positivity Preservers with constant Coefficients and their Generators

Philipp J. di Dio

In this work we study positivity preservers $T : R [x_{1}, \dots, x_{n}] \to R [x_{1}, \dots, x_{n}]$ with constant coefficients and define their generators $A$ if they exist, i.e.…
