View of Specification and Verification of Concurrent Programs

Here a substitution ' is a total function from type variables to types, from behaviour variables to behaviours, and from region variables to regions, such that all but a nite set

This dichotomy corresponds well to practice: ordinary pointers are the building material for lists and trees, whereas auxiliary pointers cor- respond to specic short cuts (such as

Labelled transition systems capturing the idea that a system has state which changes by performing actions, are used as the basic model of concurrent systems and used in giving

For feasibility reasons this statement should be read as “the verifier shall design and carry out verification activities with a view to enable a verification opinion that states

Local variables within a frame can be accessed in any order, whereas the operand stack, as the name implies, is a stack of values that are used as operands by bytecode

• Typical causes: Unfair scheduling, priorities, bad luck Livelock. • Livelock = mutual

where tenv is a type environment mapping variables to type schemes, t is the type of e and b is its be- haviour, Since CML has a call-by-value semantics there is no behaviour

in the XML specification as shown below, so that the XSLT document knows how this widget will be transformed. Since a radio button is a simple type of button, its specification
