In this talk, we investigate a new type of convergence theorem to the nucleolus of an n-person cooperative game. First, we define an lp-nucleolus as a generalization of the least square nucleolus of Ruiz et al.(1996) to a kind of lp norm minimizer. Next, we deal with the convergence of the lp-nucleolus to the nucleolus as p --> ∞. This result gives not only a new characterization of the nucleolus, but also a new approximation method to obtain the nucleolus.
