The Burden of Choice, the Complexity of the World and Its Reduction: The Game of Go/Weiqi as a Practice of "Empirical Metaphysics

The main aim of the text is to show how a game of Go (Weiqi, baduk, Igo) can serve as a model representation of the ontological-metaphysical aspect of the actor–network theory (ANT). An additional objective is to demonstrate in return that this ontological-metaphys⁠ical aspect of ANT represented on Go/Weiqi game model is able to highlight the key aspect of this theory—onto-methodological praxis

Ontological imagination: transcending methodological solipsism and the promise of interdisciplinary studies

This text is a presentation of the notion of ontological imagination. It constitutes an attempt to merge two traditions: critical sociology and science and technology studies - STS. By contrasting these two intellectual traditions, I attempt to bring together: a humanist ethical-political sensitivity and a posthumanist ontological insight. My starting point is the premise that contemporary world needs new social ontology and new critical theory based on it in order to overcome the unconsciously adapted, “slice-based” modernist vision of social ontology. I am convinced that we need new ontological frameworks of the social combined with a research disposition which I refer to as ontological imagination

Nonzero-sum Stochastic Games

This paper treats of stochastic games. We focus on nonzero-sum games and provide a detailed survey of selected recent results. In Section 1, we consider stochastic Markov games. A correlation of strategies of the players, involving ``public signals'', is described, and a correlated equilibrium theorem proved recently by Nowak and Raghavan for discounted stochastic games with general state space is presented. We also report an extension of this result to a class of undiscounted stochastic games, satisfying some uniform ergodicity condition. Stopping games are related to stochastic Markov games. In Section 2, we describe a version of Dynkin's game related to observation of a Markov process with random assignment mechanism of states to the players. Some recent contributions of the second author in this area are reported. The paper also contains a brief overview of the theory of nonzero-sum stochastic games and stopping games which is very far from being complete.average payoff stochastic games, correlated stationary equilibria, nonzero-sum games, stopping time, stopping games
