Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
The existence of approximate fixed points and approximate endpoints of the multivalued almost I-contractions is established. We also develop quantitative estimates of the sets of approximate fixed points and approximate endpoints for multivalued almost I-contractions. The proved results unify and improve recent results of Amini-Harandi (2010), M. Berinde and V. Berinde (2007), Ciric (2009), M. P. acurar and R. V. P. acurar (2007) and many others.
