Some coincidence theorems and applications
Xie Ping Ding, E Tarafdar · Bulletin of the Australian Mathematical Society · 1994
In this paper, we establish a new coincidence theorem for a Browder type set-valued mapping and an upper semi-continuous set-valued mapping with compact acyclic values in an H-space which generalises some recent results in the literature. As applications we obtain two H a type coincidence theorems and existence theorems of maximal elements for preference correspondences.
