摘要:

对于对称幺半范畴范畴(SMC)的术语,弦图是一种强大而直观的图形语法。它们在计算机科学中有许多应用,并且在其他领域,如物理学和控制理论中变得越来越相关。在许多这样的方法中,一个重要的角色是由图的方程理论,通常作为重写规则定向和应用。本文对这种形式的改写作了全面的论述。我们解释图组合类型超图,并建立精确的对应关系图重写模的SMCs的法律,一方面和双推出(DPO)重写的超图,受一个健全的条件称为凸性,另一方面。这一结果依赖于一个更一般的特征定理,在其中,我们表明,类型超图DPO重写相当于图重写模的SMCs的法律选择一个特殊的Frobenius结构。我们说明了我们的方法与终止的非交换双积分理论的证明。

英文摘要:

String diagrams are a powerful and intuitive graphical syntax for terms of symmetric monoidal categories (SMCs). They find many applications in computer science and are becoming increasingly relevant in other fields such as physics and control theory. An important role in many such approaches is played by equational theories of diagrams, typically oriented and applied as rewrite rules. This paper lays a comprehensive foundation of this form of rewriting. We interpret diagrams combinatorially as typed hypergraphs and establish the precise correspondence between diagram rewriting modulo the laws of SMCs on the one hand and double pushout (DPO) rewriting of hypergraphs, subject to a soundness condition called convexity, on the other. This result rests on a more general characterisation theorem in which we show that typed hypergraph DPO rewriting amounts to diagram rewriting modulo the laws of SMCs with a chosen special Frobenius structure. We illustrate our approach with a proof of termination for the theory of non-commutative bimonoids.
