In this paper, we introduce a new core concept called the unbinding core by extending the definition of a deviation. In the traditional definition, players deviate if a profitable allocation exists after their deviation, while our new definition requires that all possible allocations are profitable. Therefore, the unbinding core becomes a superset of the traditional core. We examine some properties of the unbinding core. A sufficient condition for the unbinding core to be nonempty is also provided.

在本文中，我们通过扩展偏差的定义引入了一个新的核心概念，称为解绑核心。在传统的定义中，参与者偏离后是否存在可获利的分配，而我们的新定义要求所有可能的分配均获利。因此，解除绑定的核心成为传统核心的超集。我们研究了解除绑定核心的一些属性。还提供了使解除绑定的核心为非空的充分条件。
