Existence and uniqueness of solution to several kinds of differential equations using the coincidence theory
(Mathematical Society of the Republic of China, 2015)
The purpose of this article is to study the existence of a coincidence point for two mappings defined on a nonempty set and taking values on a Banach space using the fixed point theory for nonexpansive mappings. Moreover, ...
