On Ekeland's variational principle for interval-valued functions with applications
Chuang-liang Zhang, Nan-jing Huang
In this paper, we obtain a version of Ekeland's variational principle for interval-value functions by means of the Dancs-Hegedus-Medvegyev theorem [14]. We also derive two versions…
