    We study the extension of dependence logic D by a majority quantifier M over finite structures. We show that the resulting logic is equi-expressive with the extension of second-order logic by second-order majority quantifiers ...
  • Durand, Arnaud; Haak, Anselm; Kontinen, Juha; Vollmer, Heribert (Saarbrücken : Dagstuhl Publishing, 2016)
    We introduce a new framework for a descriptive complexity approach to arithmetic computations. We define a hierarchy of classes based on the idea of counting assignments to free function variables in first-order formulae. ...
  • Lück, Martin (Wadern : Schloss Dagstuhl - Leibniz-Zentrum fuer Informatik GmbH, 2017)
    Modal Team Logic (MTL) extends Väänänen's Modal Dependence Logic (MDL) by Boolean negation. Its satisfiability problem is decidable, but the exact complexity is not yet understood very well. We investigate a model-theoretical ...
