Existence and Uniqueness Theorems of Ordered Contractive Map in Banach Lattices by Xingchang Li, Zhihao Wang

“…This paper presents some existence and uniqueness theorems of the fixed point for ordered contractive mapping in Banach lattices. Moreover, we prove the existence of a unique solution for first-order ordinary differential equations with initial value conditions by using the theoretical results with no need for using the condition of a lower solution or an upper solution.…”

Contract Conditions and BIM Use Effectiveness to Improve Project Performance by Francisco Villena Manzanares, Tatiana García-Segura, Eugenio Pellicer

“…Using the partial least squares structural equation modeling (PLS-SEM) method, 92 answers were analyzed, finding contractual conditions to be mediating. These results show that appropriate conditions set in a contract with regard to handling BIM technology have a positive impact on the performance and outcomes of a project. …”
