There are quite a few generalizations or applications of the 1984 minimaxinequality of Ky Fan compared with his original 1972 minimax inequality. In a certainsense, the relationship between the 1984 inequality and several hundreds of known generalizationsof the original 1972 inequality has not been recognized for a long period. Hence,it would be necessary to seek such relationship. In this paper, we give several generalizationsof the 1984 inequality and some known applications in order to clarify the closerelationship among them. Some new types of minimax inequalities are added.
