A Mean Ergodic Theorem for Nonexpansive Mappings in Hadamard spaces
Hadi Khatibzadeh, Hadi Pouladi
In this paper, we prove a mean ergodic theorem for nonexpansive mappings in Hadamard (nonpositive curvature metric) spaces, which extends the Baillon nonlinear ergodic theorem. The…
Tauberian Conditions for Almost Convergence in a Geodesic Metric Space
Hadi Khatibzadeh, Hadi Pouladi
In the present paper, after recalling the Karcher mean in Hadamard spaces, we study the relation between convergence, almost convergence and mean convergence (respect to the define…
Almost Periodicity and Ergodic Theorems for Nonexpansive Mappings and Semigroups in Hadamard Spaces
Hadi Khatibzadeh, Hadi Pouladi
The main purpose of this paper is to prove the mean ergodic theorem for nonexpansive mappings and semigroups in locally compact Hadamard spaces, including finite dimensional Hadama…
On the Iterations of a Sequence of Strongly Quasi-nonexpansive Mappings with Applications
Hadi Khatibzadeh, Vahid Mohebbi
In this paper, we study - convergence of iterations for a sequence of strongly quasi-nonexpansive mappings as well as the strong convergence of the Halpern type regularization o…
Proximal Point Algorithm for Quasi-convex Minimization Problems in metric spaces
Hadi Khatibzadeh, Vahid Mohebbi
In this paper, the proximal point algorithm for quasi-convex minimization problem in nonpositive curvature metric spaces is studied. We prove -convergence of the generated seque…
Monotone and Pseudo-Monotone Equilibrium Problems in Hadamard Spaces
Hadi Khatibzadeh, Vahid Mohebbi
We study equilibrium problems in Hadamard spaces, which extend variational inequalities and many other problems in nonlinear analysis. In this paper, first we study the existence o…
