Talk:Polarized linear logic
Positive and negative formula
The notion of positive and negative formulas in polarized linear logic is a restriction of the more general one from linear logic. The relation might have to be clarified.
As mentioned in Talk:Positive_formula, we should also decide how to deal with the two dual notions.

I am not sure I like the presentation with a stoup. I prefer to see the at most one formula property as a lemma consequence of the definition of the rules.
But maybe I am too much a fundamentalist in this topic ...
