A super-envy-free division is a kind of a fair division. It is a division of resources among n partners, in which each partner values his/her share at strictly more than his/her due share of 1/n of the total value, and simultaneously, values the share of every other partner at strictly less than 1/n. Formally, in a super-envy-free division of a resource C among n partners, each partner i, with value measure Vi, receives a share Xi such that:
V i > V i / n and ∀ j ≠ i : V i < V i / n {\displaystyle V_{i}>V_{i}/n~~{\text{ and }}~~\forall j\neq i:V_{i} This is a strong fairness requirement: it is stronger than both envy-freeness and super-proportionality.
