abstract = "In this article infinite minimum cost spanning tree situations and related TU-games are studied. Since an optimal tree for these situations does not always exist, it is impossible in such situations to implement core solutions based on a particular tree. Therefore, we study core-like solutions and deal with three cases concerning the total cost of connection: when it is zero, when it is finite but larger than zero, and when it is infinite.",
