Archimedean Representation Theorem for modules over a commutative ring

Colin Tan

Pólya's Positivstellensatz and Handelman's Positivstellensatz are known to be concrete instances of the abstract Archimedean Representation Theorem for (commutative unital) rings.…

A Positivstellensatz for forms on the positive orthant

Claus Scheiderer, Colin Tan

Let $p$ be a nonconstant form in $R [x_{1}, \dots, x_{n}]$ with $p (1, \dots, 1) > 0$ . If $p^{m}$ has strictly positive coefficients for some integer $m \geq 1$ , we show that $p^{m}$ has str…
