We present a general theorem capturing conditions required for the termination of abstract reduction systems. We show that our theorem generalises another similar general theorem about termination of such systems. We apply our theorem to give interesting proofs of termination for typed combinatory logic. Thus, our method can handle most path-orderings in the literature as well as the reducibility method typically used for typed combinators. Finally we show how our theorem can be used to prove termination for incrementally defined rewrite systems, including an incremental general path ordering. All proofs have been formally machine-checked in Isabelle/HOL.

Системы переписывания процессов (Process Rewrite Systems - PRS) Ричарда Майра представляют собой систему переписывания термов специального вида и задают унифицированное представление для конечных и магазинных автоматов, сетей Петри и некоторых классов алгебр процессов. В докладе рассматривается (P,P)-подкласс систем переписывания процессов, соответствующий классическим сетям Петри, и его расширение HPRS для моделирования систем с динамической структурой. Обсуждаются вопросы выразительности и разрешимости.
