Title: PROOF RULES FOR DYNAMIC PROCESS CREATION AND DESTRUCTION
Authors: Limor Fix and Nissim Francez
PDFCS0647.pdf
Abstract: The paper presents proof-roles for partial-correcUles8 of dynamic concurrency. by which processes are dynamically created and destroyed during the execution of a concurrent program. Both message-passing concurrency and shared-variables concurrency are considered. For the latter, the paper presents also a proof method for deadlock freedom. The proofs-rules are canonical and present several proof-theoretical issues absent in previous static proof-systems. In particular, both interference-freedom and cooperation are needed in both models. Several examples of applications of the rule are presented
