The existence results of these two problems are proved by using the hybrid fixed point theorem for three operators in a Banach algebra and the generalized Krasnoselskii's fixed point theorem, respectively. � 2018 Saowaluck Chasreechai and Thanin Sitthiwirattham.All Open Access; Gold Open Access; Green Open AccessArticleScopus
