Abstract
A certain subset of temporal properties defined using local variables can be formally verified with complexity of PSPACE or less. A subset with this characteristic, referred to as a practical subset, is therefore feasible to formally verify. For example, it can be shown that temporal properties that possess an alternating automaton with no conflicts fall within a practical subset. Temporal properties are analyzed to determine whether they are a member of the practical subset. Members of the practical subset can then be feasibly formally verified.
