Hyperbolic monotonicity in the Hilbert ball
Fixed Point Theory and Applications volume 2006, Article number: 78104 (2006)
Abstract
We first characterize -monotone mappings on the Hilbert ball by using their resolvents and then study the asymptotic behavior of compositions and convex combinations of these resolvents.
