  1. (Paritosh Pandya, Simoni Shah) NEW INSIGHTS IMPACT STATUS QUO LONG TERM GOALS Unambiguity In Time We introduce Partially Ordered 2-way Deterministic Timed Automata (po2DTA)‏ Timed- Unambiguous Interval Logic (T-UIL)‏ po2DTA ≡ T-UIL po2DTA: Small Model for po2DTA: A po2DTA with n states has a “small model” of size atmost n^2 Satisfiability is NP-complete Timed-UIL : Unambiguous chop- wrt the letter and a time constraint 2-NTA –reversal bounded: Satisfiability is in PSPACE Fully decidable timed automata, and logics in real time PROBLEM We have a 2- way DTA, which is reversal bounded due to partial order NTA- complementation undecidable Equivalent logical characterizations Finding a monadic-logic characterization for the same class. We have a boolean-closed timed automaton and logic with NP-complete satisfiability.
