Formal Systems
Over the years, several different formal systems have been developed which permit reasoning about systems in the Actor model. These include:
- Operational semantics
- Laws for Actor systems
- Denotational semantics
- Transition semantics
There are also formalisms that are not fully faithful to the Actor model in that they do not formalize the guaranteed delivery of messages including the following (See Attempts to relate Actor semantics to algebra and linear logic):
- Several different Actor algebras
- Linear logic

Famous quotes containing the words formal and/or systems:
“It is in the nature of allegory, as opposed to symbolism, to beg the question of absolute reality. The allegorist avails himself of a formal correspondence between “ideas” and “things,” both of which he assumes as given; he need not inquire whether either sphere is “real” or whether, in the final analysis, reality consists in their interaction.”
—Charles, Jr. Feidelson, U.S. educator, critic. Symbolism and American Literature, ch. 1, University of Chicago Press (1953)
“No civilization ... would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.”
—Hannah Arendt (1906–1975)
