Abstract:
In this paper, we extended the notion of diagonally quasiconvexity
for multifunctions and established several existence results for
zeros of diagonally quasiconvex multifunctions. As applications we
obtain the results of fixed points, coincidence points and best
approximations for multifunctions. Using our result we also prove
the existence of solutions to the variational-like inequality
problem and generalized vector equilibrium problem. The results
of this paper generalize some known results in the literature.
