Center node: "begin after and later a maximal decidable interval temporal logic"
  Abstract: Interval temporal logics (ITLs) are logics for reasoning ab out temporal statements expressed over intervals, i.e., periods of time. The most famous ITL studied so far is Halpern and Shoham’s HS, which is the logic of the thirteen Allen’s interval relations. Unf ortunately, HS and most of its fragments have an undecidable satisfiability problem. This discouraged th e research in this area until recently, when a number non-trivial decidable ITLs have been discovered. This paper is a contribution towards the complete classification of all different fragments of HS. We consider different combinations of the interval relations begins (B), after (A), later (L) and their inverses A, B andL. We know from previous works that the combinationABBA is decidable only when finite domains are considered (and undecidable elsewhere), and thatABB is decidable over the natural numbers. We extend these results by showing that decidability ofABB can be further extended to capture the languageABBL, which lies in between ABB andABBA, and that turns out to be maximal w.r.t decidability over str ongly discrete linear orders (e.g. finite orders, the naturals, th e integers). We also prove that the proposed decision procedure is optimal with respect to the EXPSPACE complexity class.
