Abstract:

We give a new characterization of those languages that are definable in fragments of LTL where the nesting depths of X and U modalities are bounded by given constants. This brings further results about various LTL fragments. We also propose a generic method for decomposing LTL formulae into an equivalent disjunction of ``semantically refined" LTL formulae, and indicate how this result can be used to improve the functionality of existing LTL model-checkers.
