Proving Properties of Actor Systems
Carl Hewitt published the principle of Actor induction which is:
- Suppose that an Actor x has property P when it is created
- Further suppose that if x has property P when it processes a message, then it has property P when it processes the next message.
- Then x always has the property P.
In his doctoral dissertation, Aki Yonezawa developed further techniques for proving properties of Actor systems including those that make use of migration. Russ Atkinson and Carl Hewitt developed techniques for proving properties of Serializers that are guardians of shared resources. Gerry Barber's doctoral disseration concerned reasoning about change in knowledgeable office systems.

Famous quotes containing the words proving, properties, actor and/or systems:
“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.”
—Anton Pavlovich Chekhov (1860–1904)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
“When an actor has money, he sends not letters, but telegrams.”
—Anton Pavlovich Chekhov (1860–1904)
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
