WebJul 5, 2024 · 1 Answer Sorted by: 0 Given a constructive ordered field $K$, the field $K (t)$ of rational functions can be given the minimal order structure inherited from $K$ and $t > 0$. That is, two rational functions $f (t), g (t)$ have $f (t) < g (t)$ if that is derivable from order information on $K$ and $t > 0$.

WebFeb 1, 1996 · The aim of this paper is to introduce a new approach to the modal operators of necessity and possibility. This approach is based on the existence of two negations in certain lattices that we call bi-Heyting algebras. Modal operators are obtained by iterating certain combinations of these negations and going to the limit.
