Maximal nonnegative and $\theta$-accretive extensions of a positive definite linear relation
Karpatsʹkì Matematičnì Publìkacìï, 2020 Let $L_{0}$ be a closed linear positive definite relation ("multivalued operator") in a complex Hilbert space. Using the methods of the extension theory of linear transformations in a Hilbert space, in the terms of so called boundary value spaces ...

Journal of Inequalities and Applications, 2007 A new class of generalized nonlinear set-valued quasivariational inclusions involving generalized m-accretive mappings in Banach spaces are studied, which included many variational inclusions studied by others in recent years. By using the properties of

Adaptive Mann iterations for nonlinear accretive and pseudocontractive operator equations [PDF]
, 2008 We construct adaptive Mann iterations for finding fixed points of strongly pseudocontractive mappings and solving nonlinear strongly accretive (not necessary continuous) operator equation Sx = f in p-smooth Banach ...

Approximations of Antieigenvalue and Antieigenvalue-Type Quantities
International Journal of Mathematics and Mathematical Sciences, 2012 We will extend the definition of antieigenvalue of an operator to antieigenvalue-type quantities, in the first section of this paper, in such a way that the relations between antieigenvalue-type quantities and their corresponding Kantorovich-type ...

Weak convergence of an iterative sequence for accretive operators in Banach spaces
Fixed Point Theory and Applications, 2006 Let C be a nonempty closed convex subset of a smooth Banach space E and let A be an accretive operator of C into E. We first introduce the problem of finding a point u∈C such that 〈Au,J(v−u)〉≥0 for all v∈C ...

A Note on Solvability of the Nonlinear Abstract Viscoelastic Problem in Banach Spaces
Trends in Computational and Applied Mathematics, 2000 In this work we are concerned with the existence of integral solution for a nonlinear abstract viscoelastic problem in a Banach space where the operator is accretive and time dependent.

Some Properties of M-Accretive Operators in Normed Spaces
, 2015 Multivalued mapping in normed space has been extensively studied in Mathematical analysis. One example of multivalued mapping is normalized duality mapping. This mapping leads us to another example of multivalued operator, named accretive operator, which
