Kooperativní hry s částečnou informací

Černý, Martin

(english) May 21, 2021 Partially defined cooperative games are a generalisation of classical coopera- tive games in which the worth of some of the coalitions is not known. Therefore, they are one of the possible approaches to uncertainty in cooperative game the- ory. The main focus of this thesis is to collect and extend the existing results in this theory. We present results on superadditivity, convexity, positivity and 1-convexity of incomplete games. For all the aforementioned properties, a de- scription of the set of all possible extensions (complete games extending the incomplete game) is studied. Different subclasses of incomplete games are con- sidered, among others incomplete games with minimal information, incomplete games with defined upper vector or symmetric incomplete games. Some of the results also apply to fully generalised games. For superadditivity and 1-convexity, solution concepts (considering only par- tial information) are introduced and studied. Especially for 1-convexity, a thor- ough investigation of the defined solution concepts consisting of different char- acterisations is provided. 1
