$\delta$-sequences and Evaluation Codes defined by Plane Valuations at Infinity

C. Galindo, F. Monserrat

We introduce the concept of $\delta$-sequence. A $\delta$-sequence $\Delta$ generates a well-ordered semigroup $S$ in ${\mathbb{Z}}^2$ or $\mathbb{R}$. We show how to construct (and compute paramet…
