异步$π$演算中同步码编码的有效性

On the Validity of Encodings of the Synchronous in the Asynchronous $π$-calculus

Rob van Glabbeek

摘要:

进程演算可以通过它们之间的编码来比较它们的表达能力。Gorla提出了一个被广泛接受的定义,定义了什么构成了一个有效的编码,用于证明过程演算之间的相对表达性结果。在这项工作之前,不同的编码和分离结果通常是使用不同的,往往是不兼容的,编码的质量标准。有效编码的教科书例子是Boudol和Honda & Tokoro提出的将同步无选择$π$ -演算编码到其异步片段中的编码,说明后者的表达能力不亚于前者。在这里,我正式确定这些编码确实满足Gorla的标准。

英文摘要:

Process calculi may be compared in their expressive power by means of encodings between them. A widely accepted definition of what constitutes a valid encoding for (dis)proving relative expressiveness results between process calculi was proposed by Gorla. Prior to this work, diverse encodability and separation results were generally obtained using distinct, and often incompatible, quality criteria on encodings. Textbook examples of valid encoding are the encodings proposed by Boudol and by Honda & Tokoro of the synchronous choice-free $π$-calculus into its asynchronous fragment, illustrating that the latter is no less expressive than the former. Here I formally establish that these encodings indeed satisfy Gorla's criteria.
