The Karush–Kuhn–Tucker conditions for the semi-infinite interval programming problem are particular cases of those found in this paper for constrained equilibrium problem.We illustrate this with some examples. In addition, we obtain solutions to the interval equilibrium problem in the unconstrained case. The results presented in this paper extend the corresponding results in the literature.}, organization = {The research has been supported by FEDER Andalucía 2014-2020 (UPO-1381297) and by MICIN through grant MCIN/AEI/PID2021-123051NB-100.}, publisher = {Springer}, keywords = {Equilibrium problem}, keywords = {Semi-infinite programming}, keywords = {Interval-valued functions}, title = {Semi-infinite interval equilibrium problems: optimality conditions and existence results}, doi = {10.1007/s40314-023-02378-8}, author = {Ruiz Garzón, Gabriel and Osuna Gómez, Rafaela and Rufián Lizana, Antonio and Beato-Moreno, Antonio}, }
