On A Fixed Point Theorem For The Product Of Operators
, 2017 In this paper, we study the existence of fixed points for the product of nonlinear operators. This kind of fixed point theorems is necessary in consideration of quadratic differential and integral problems.

Some new fixed point results in b-metric spaces
Topological Algebra and its Applications, 2018 In this paper, we consider, discuss, improve and generalize recent fixed point results for mappings in b-metric space. These results are generalizations of the analogous ones recently proved by Khojasteh et al. [12] and Demma et al. [8].

Referral Patterns and Diagnostic Timeliness in Pediatric Cancer: A Hospital‐Based Study in Indonesia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Timely diagnosis and treatment are critical for improving survival among children with cancer. In low‐ and middle‐income countries (LMICs), delays are common and may be influenced by fragmented referral pathways and diagnostic limitations.

Transactions of A. Razmadze Mathematical Institute, 2018 Jleli and Samet (2018) introduced a new metric space and named it as F -space. In this paper we consider the notion of α - ψ -contraction in the setting of F -metric spaces.

New Fixed Point Results for Modified Contractions and Applications [PDF]
Symmetry, 2019 In this study, we introduce a new type of contractive mapping to establish the existence and uniqueness of fixed points for this type of contraction. Some related examples are built demonstrating the superiority of our results compared to the existing onesin the literature.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Latino children are projected to make up nearly one‐third of United States (US) children by 2060, and many of their caregivers speak Spanish. Prior survey research has documented communication difficulties for Spanish‐speaking caregivers of children with cancer, but contemporary qualitative data are limited.

Measures of weak noncompactness and fixed point theory in banach algebras satisfying condition (P)
, 2017 The aim of this paper is to prove some new fixed point theorems in a nonempty closed convex subset of a Banach algebra satisfying a sequential condition (P) in a weak topology setting.peer ...

Some fixed point results for a new three steps iteration process in banach spaces [PDF]
, 2017 In this paper, we introduce a three step iteration method and show that this method can be used to approximate fixed point of weak contraction mappings. Furthermore, we prove that this iteration method is equivalent to Mann iterative scheme and converges
