Semantics of LTL
A transition system M=(S,→,L) is a set of states S endowed with a transition relation → (a binary relation), such that every s ∈ S has some s’∈ S with s → s’, and a labeling function L: S →P(Atoms). Transition systems are also simply called models. a model has a collection of states S, a relation →,saying how the system can move from state to state, and, associated with each state s, one has the set of atomic propositions L(s)which are true at that particular state. L is that it is just an assignment of truth values to all the propositional atoms. A transition system has more than one state, so this assignment depends on which state s the system is in: L(s) contains all atoms which are true in state s. All the information about a (finite) transition system M always be figured by using directed graphs whose nodes (which we call states) contain all propositional atoms that are true in that state. For example, if our system has only three states s0, s1 and s2; if the only possible transit
