- Abstract
In this paper, with a view to improve the g-monotonicity condition, we introduce the notion of g-comparability of a mapping deffined on an ordered set and utilize the same to prove some existence and uniqueness results on coincidence points for linear contraction without g-monotonicity in ordered metric spaces. Our results extend some classical and well known results due to Ran and Reurings (Proc. Amer. Math. Soc. 132(2004), no.5, 1435-1443), Nieto and Rodríguez-López (Acta Math. Sin. 23(2007), no.12, 2205-2212), Turinici (Libertas Math. 31(2011), 49-55), Turinici (Math. Student 81(2012), no.1-4, 219-229) and Dorić et al: (RACSAM 108(2014), no.2, 503-510) and similar others.
