Amina Doumane (Université Paris Diderot and ENS Cachan), On the dependencies of logical rules



Many correctness criteria have been proposed since linear logic was introduced and it is not clear how they relate to each other. We present proof-nets and their correctness criteria from the perspective of dependency, as introduced by Mogbil and Jacobé de Naurois.

More precisely, we introduce a new correctness criterion, called DepGraph, and show that together with Danos' contractibility criterion and Mogbil and Naurois criterion, they form the three faces of a notion of dependency which is crucial for correctness of proof-structures.

Finally, we extract the logical meaning of the dependency relation and show that it allows to recover and characterize some constraints on the ordering of inferences which are implicit in the proof-net.
