Intervals may be used in expressions in various ways, using the following operators (table Given an interval I we have the following two operations on intervals. In order to reason within our logic we need to define some basic operators, in addition to the standard first-order logic with its boolean operators (disjunction), (conjunction), (negation), (implication) and (equivalence). We also have the first order operators (existence), and (universality). Following Manna and Pnueli [ , the temporal operators in table are sufficient for our purposes. Table: operators. p and q are general propositions. for intervals. Note that some of these operators are `weak' versions: wait-for is a weak version of the until operator which allows for the possibility that q never occurs and, then

Temporal Logics Connections Related to: Prerequisites: Formal Systems Classical Modal Requisite for: Tableau rules for modal logic Temporal logics are designed to express temporal progression. It is customary to add the operator [] with the interpretation determined by the logic. A second operator is the dual of the first i.e. A = ¬[]¬A and []A = ¬ ¬A. Figure 1 illustrates some readings of the formulas []A and A. Temporal logic plays an important role in the specification, derivation, and verification of programs as programs may be viewed as progressing through a sequence of states, a new state after each event in the system. They have a particularly useful role in the specification and verification of communication protocols and reactive systems. Propositional temporal logics have the finite model property making them useful for the derivation of programs from formal specifications.  The derived model resembles a finite state machine hovever, the model accepts infinite strings and belongs to the class of w -automata. Without the addition of additional temporal operators, temporal logic cannot express all regular expressions.

52. TIME International Symposium Series The annual International Workshop on temporal Representation and Reasoning covers temporal representation and reasoning, including temporal logic. http://www.cs.uregina.ca/~temporal/

TIME International Symposium Series You have reached the old web site for the TIME International Symposium Series. The new web site is at http://time.dico.unimi.it The TIME International Symposium Series began in 1994. The first six annual meetings were held as workshops in conjunction with the FLAIRS (Florida Artificial Intelligence Research Society) annual conference. As the workshop has grown, the participants decided to hold the annual meeting as an independent event. Since its inception, the purpose of this symposium series has been to bring together active researchers in the area of temporal representation and reasoning in Artificial Intelligence. Through paper presentations and discussions, the participants will exchange, compare, and contrast results in the area. Over the years, participation of researchers from areas outside of mainstream AI (especially the database community) has grown. For this reason, beginning with TIME-2001, we have opened the meeting to active researchers in temporal (including temporal-spatial) representation and reasoning from all areas. Additionally, the annual meeting has matured and the format has evolved to the point where it is more appropriately identified as a symposium rather than a workshop. Also, beginning with TIME-2001, we have adopted a track format for the symposium. For information about the current or previous meetings, follow the appropriate link below.

58. Basic Temporal Logic Basic temporal logic. Accordingly, the minimal temporal logic is axiomatizedby adding to system K the axiom (4), which corresponds to transitivity. http://www.informatik.uni-leipzig.de/~duc/Thesis/node52.html

Next: Propositional Dynamic Logic Up: Modal logic Previous: Montague-Scott semantics Contents Basic temporal logic The reading of the operator as ``always in the future'' (and accordingly, as ``sometimes in the future'') has proved plausible for many modal logics. Those systems are the most simple temporal (or tense) logics. Semantically, the ``possible worlds'' of a Kripke model are interpreted as moments in time, and the accessibility relation is viewed as the the relation ``later than''. Clearly, not all algebraic properties that can be imposed on binary relations are meaningful under a temporal interpretation. The most interesting properties are those characterizing ordering relations. Transitivity is probably the most basic condition that can be placed on the relation ``later than'', so it is typically assumed that temporal structures are transitive. Accordingly, the minimal temporal logic is axiomatized by adding to system K the axiom , which corresponds to transitivity. That system is denoted K , with the subscript indicating that a temporal logic is being considered.

The Free Online Dictionary of Computing ( http://foldoc.doc.ic.ac.uk/ dbh@doc.ic.ac.uk Previous: temporal database Next: Tempura temporal logic logic predicate calculus which includes notation for arguing about *when* statements are true. Time is discrete and extends indefinitely into the future. Three prefix operators, represented by a circle, square and diamond mean "is true at the next time instant", "is true from now on" and "is eventually true". x U y means x is true until y is true. x P y means x precedes y. There are two types of formula: "state formulae" about things true at one point in time, and "path formulae" about things true for a sequence of steps. An example of a path formula is "x U y", and example of a state formula is "next x" or a simple atomic formula such at "waiting". "true until" in this context means that a state formula holds at every point in time up to a point when another formula holds. "x U y" is the "strong until" and implies that there is a time when y is true. "x W y" is the "weak until" in which it is not necessary that y holds eventually. There are two types of temporal logic used: branching time and linear time. The basic propositional temporal logic cannot differentiate between the two, though. Linear time considers only one possible future, in branching time you have several alternative futures. In branching temporal logic you have the extra operators "A" (for "all futures") and "E" (for "some future"). For example, "A(work U go_home)" means "I will work until I go home" and "E(work U go_home)" means "I may work until I go home".

From Computer-Aided Verification (CAV '94) Edited by David Dill. Springer-Verlag, Stanford, CA. June, 1994. Abstract: We present a new temporal logic, GTL, appropriate for specifying properties of hardware at the register transfer level. We argue that this logic represents an improvement over model checking for some natural hardware verification problems. We show that the validity problem for this logic is Pi 1-1 complete. We then identify a fragment of the logic that is decidable. We show that in this fragment we are still able to encode many interesting problems, including the correctness of pipelined microprocessors.
