Abstract
A layered semantics model of an object-based concurrent programming language is proposed, which provides a support for reasoning of object compositions. Upon construction and verification of a concurrent program, a mechanism which supports compositions of object descriptions and a technique which supports compositional reasoning are desirable. However, compositional semantics of a sufficiently rich concurrent language tends to be complicated so as to cope with rare anomalies.
In order to overcome this difficulty, a layered scheme is introduced: the bottom layer is based on a transition system and the top layer is based on the notion of program transformation, which supports compositional reasoning at least in some degree. Since more abstract descriptions rely on more concrete descriptions, all layers are not necessarily self-contained. By this scheme, information necessary for composition can be hidden away in abstract layers. Based on the layered semantics, each proof and reasoning should be performed in an appropriate level of abstraction.
