Ekeland-type variational principle with applications to nonconvex minimization and equilibrium problems
The aim of the present paper is to establish a variational principle in metric spaces without assumption of completeness when the involved function is not lower semicontinuous. As consequences, we derive many fixed point results, nonconvex minimization theorem, a nonconvex minimax theorem, a noncon...
