A NEW DEFINITION OF PROOF-NETS
一个新的证明网定义及合理性

This paper presents a new definition of proof-net and proves that what the authors defined is the "natural deduction of linear logic". The complealty of deciding whether a given proof structure is a proof-net by definition is O(n * n), by the way, the proof of sequentialization of proof-nets so defined is very natural and simple.
