Center node: "proof nets for the lambek grishin calculus"
  Abstract: Grishin's generalization of Lambek's Syntactic Calculus combines a non-commutative multiplicative conjunction and its residuals (product, left and right division) with a dual family: multiplicative disjunction, right and left difference. Interaction between these two families takes the form of linear distributivity principles. We study proof nets for the Lambek-Grishin calculus and the correspondence between these nets and unfocused and focused versions of its sequent calculus.

Connected through hyperedge HE-1 (induced by source paper "a proof theoretic approach to scope ambiguity in compositional vector space models"):
