English summary: This volume presents eight contributions by representatives of classical philology, church history, philosophy and religious studies, dealing with elucidating the possible relations between Origen the Christian theologian and Origen the Platonic philosopher. Thus, the volume contains discussions of the - not yet conclusively answered - question of whether the Christian Origen and the Platonic Origen might in fact have been one and the same person; it also investigates the Platonic traits of the Christian Origen, which are easily recognizable (...) in some of his works, and the reception both the philosopher and the Christian Origen had in late antiquity, in authors such as the Platonists Porphyry and Proclus as well as the Christian theologian Eusebius of Caesarea. German description: Der hier vorgelegte Band versammelt insgesamt acht Beitrage (von Vertretern der Klassischen Philologie, der Kirchengeschichte, der Philosophie und der Religionswissenschaft), die sich mit den moglichen Beziehungen zwischen dem christlichen Theologen Origenes und dem platonischen Philosophen Origenes beschaftigen. Dabei geht es nicht nur um die (immer noch nicht abschliessend beantwortete) Frage, ob der Christ Origenes und der Platoniker Origenes vielleicht sogar dieselbe Person sind, sondern auch um den (in manchen Werken deutlich erkennbaren) Platonismus des christlichen Theologen Origenes und die Rezeption dieses oder dieser Origene(i)s in der Spatantike: bei den Platonikern Porphyrios und Proklos und bei dem christlichen Theologen Eusebius von Caesarea. Mit Beitragen von: Balbina Babler, Peter Gemeinhardt, Jens Halfwassen, Theo Kobusch, Winrich Lohr, Heinz-Gunther Nesselrath, Christoph Riedweg, Ilinca Tanaseanu-Dobler, Andrea Villani. (shrink)

We propose a method to associate a coalitional interval game with each strategic game. The method is based on the lower and upper values of finite two-person zero-sum games. Associating with a strategic game a coalitional interval game we avoid having to take either a pessimistic or an optimistic approach to the problem. The paper makes two contributions to the literature: It provides a theoretical foundation for the study of coalitional interval games and it also provides, studies, and characterizes a (...) natural method of associating coalitional interval games with strategic games.
