TU-games with utility: the u-prenucleolus 

The u-prenucleolus is a generalisation of the prenucleolus using utility functions. The u-prenucleolus also can be considered as a generalisation of the per-capita prenucleolus. We prove a generalisation of Kohlberg’s theorem to the u-prenucleolus and a generalisation of Katsev and Yanovskaya’s theorem, thereby giving a sufficient and necessary condition on the unicity of the u-prenucleolus. We also define the u-essential coalitions which give a characterisation set for the u-prenucleolus. Special cases of this result give a characterisation set for the per-capita prenucleolus on balanced games and a characterisation set for the prenucleolus on certain non-balanced games. 

The talk is based on joint work with Miklós Pintér.
