Applications between sport management and game theory: A case study on 21st Summer Deaflympics

This note is devoted to provide some applications between sport management and game theory. In this note, we study some game-theoretical definitions and the duplicate core proposed by Hwang and Liao. Subsequently, we also try to investigate the relationship and the coincidence between the duplicate core and the 21st Summer Deaflympics by means of the axiomatizations of the duplicate core proposed by Liao.
