Center node: "conway games algebraically and coalgebraically"
  Abstract: Using coalgebraic methods, we extend Conway's theory of games to possibly#N#non-terminating, i.e. non-wellfounded games (hypergames). We take the view that#N#a play which goes on forever is a draw, and hence rather than focussing on#N#winning strategies, we focus on non-losing strategies. Hypergames are a#N#fruitful metaphor for non-terminating processes, Conway's sum being similar to#N#shuffling. We develop a theory of hypergames, which extends in a non-trivial#N#way Conway's theory; in particular, we generalize Conway's results on game#N#determinacy and characterization of strategies. Hypergames have a rather#N#interesting theory, already in the case of impartial hypergames, for which we#N#give a compositional semantics, in terms of a generalized Grundy-Sprague#N#function and a system of generalized Nim games. Equivalences and congruences on#N#games and hypergames are discussed. We indicate a number of intriguing#N#directions for future work. We briefly compare hypergames with other notions of#N#games used in computer science.
