    Ebbing, Johannes; Kontinen, Juha; Mueller, Julian-Steffen; Vollmer, Heribert (Braunschweig : Tech. Univ. Braunschweig, 2014)
    In this paper we study the expressive power of Horn-formulae in dependence logic and show that they can express NP-complete problems. Therefore we define an even smaller fragment D*-Horn and show that over finite successor ...
