Δ-convergence for proximal point algorithm and fixed point problem in CAT(0) spaces
Fixed Point Theory and Applications, 2019 In this paper, we prove the Δ-convergence of a modified proximal point algorithm for common fixed points in a CAT(0) space for different classes of generalized nonexpansive mappings including a total asymptotically nonexpansive mapping, a multivalued ...

Demonstratio Mathematica, 2019 We consider a new subgradient extragradient iterative algorithm with inertial extrapolation for approximating a common solution of variational inequality problems and fixed point problems of a multivalued demicontractive mapping in a real Hilbert space ...

Woody Plant Encroachment, Grassland Loss, and Farm Subsidies
Journal of Agricultural Economics, Volume 76, Issue 3, Page 570-581, September 2025.ABSTRACT The UN Decade on Ecosystem Restoration (2021–2030) aims to prevent the degradation of ecosystems, such as grasslands, which play a key role in the provision of biodiversity, forage, and cultural ecosystem services. However, woody plant encroachment increasingly causes the loss of grasslands, which provide forage, are biodiversity hotspots, and

Journal of Applied Mathematics, 2012 An iterative sequence for quasi--asymptotically nonexpansive multivalued mapping for modifying Halpern's iterations is introduced. Under suitable conditions, some strong convergence theorems are proved.

Analysis of density matrix embedding theory around the non‐interacting limit
Communications on Pure and Applied Mathematics, Volume 78, Issue 8, Page 1359-1410, August 2025.Abstract This article provides the first mathematical analysis of the Density Matrix Embedding Theory (DMET) method. We prove that, under certain assumptions, (i) the exact ground‐state density matrix is a fixed‐point of the DMET map for non‐interacting systems, (ii) there exists a unique physical solution in the weakly‐interacting regime, and (iii ...

On Some Problems with Multivalued Mappings
Automation and Remote ControlWe consider some problems with a set-valued mapping, which can be reduced to minimization of a homogeneous Lipschitz function on the unit sphere. Latter problem can be solved in some cases with a first order algorithm—the gradient projection method. As one of the examples, the case when set-valued mapping is the reachable set of a linear autonomous ...

Multivalued maps and the existence of best approximants
Journal of Approximation Theory, 1991 AbstractSome existence of the best approximants in normed linear space is presented. A fixed point theorem for uppersemicontinuous multivalued maps with nonconvex values is used for this purpose. Previous results due to different authors are covered and extended through our method.

Some Convergence Theorems of Modified Proximal Point Algorithms for Nonexpansive Mappings in CAT(0) Spaces [PDF]
Results in Nonlinear Analysis, 2018 In this paper, a new modified proximal point algorithm is proposed for finding a common element of the set of fixed points of a single-valued nonexpansive mapping, and the set of fixed points of a multivalued nonexpansive mapping, and the set of ...

Fixed Point of Almost Contraction in b-Metric Spaces
Journal of Mathematics, 2020 In this paper, we introduce a generalized multivalued (α, L)-almost contraction in the b-metric space. Furthermore, we prove the existence and uniqueness of the fixed point for a specific mapping.
