%0 Journal Article %T Reducing Validity in Epistemic ATL to Validity in Epistemic CTL %A Dimitar P. Guelev %J Electronic Proceedings in Theoretical Computer Science %D 2013 %I Open Publishing Association %R 10.4204/eptcs.112.13 %X We propose a validity preserving translation from a subset of epistemic Alternating-time Temporal Logic (ATL) to epistemic Computation Tree Logic (CTL). The considered subset of epistemic ATL is known to have the finite model property and decidable model-checking. This entails the decidability of validity but the implied algorithm is unfeasible. Reducing the validity problem to that in a corresponding system of CTL makes the techniques for automated deduction for that logic available for the handling of the apparently more complex system of ATL. %U http://arxiv.org/pdf/1303.0794v1
