The existence and uniqueness of fixed points of such maps are discussed both on metric spaces and on partially ordered metric spaces. The results are applied to a first order periodic boundary value problem.eninfo:eu-repo/semantics/openAccesspartial orderfixed pointboundary value problemArticleQ1WOS:000347388400001
