*Correspondence: [email protected] Faculty of Mathematics and Informatics, University of Plovdiv, Plovdiv, 4000, Bulgaria Abstract In this paper, we establish a full statement of Ćirić’s fixed point theorem in the setting of cone metric spaces. More exactly, we obtain a priori and a posteriori error estimates for approximating fixed points of quasi-contractions in a cone metric space. Our ...

Abstract We studied the evolution of an isolated pulsed plasma in a vortex flow stabilised microwave (MW) discharge N 2 at 25 mbar via combination 0D kinetics modelling, iCCD imaging and laser scattering diagnostics. Quenching electronically excited results fast gas heating onset thermal-ionisation instability, contracting volume. The instability driven by vibrational excitation pathways is fou...

Abstract. In this paper, we introduce contractive conditions of integral type in the setting of dislocated quasi b-metric spaces. Using contractive conditions of integral type, we have presented a fixed point theorem in the framework of dislocated quasi b-metric spaces. Our established result generalize and extend various fixed point theorems of the literature in the context of dislocated quasi...

It is generally conjectured that the Mann iteration converges faster than the Ishikawa iteration for any operator defined on an arbitrary closed convex subset of a Banach space. The recent result of Babu et al [1] shows that this conjecture can be proved for a class of quasi-contractive operators called the Zamfirescu operators[10]. In this paper it is shown that the proof can indeed be general...

We consider non-conservative positive semigroups and obtain necessary sufficient conditions for uniform exponential contraction in weighted total variation norm. This ensures the existence of Perron eigenelements provides quantitative estimates spectral gap, complementing Krein–Rutman theorems generalizing probabilistic approaches. The proof is based on a non-homogenous h $h$ -transform semigro...

In this paper, we present a new concept of random contraction and prove a coupled random fixed point theorem under this condition which generalizes stochastic Banach contraction principle. Finally, we apply our contraction to obtain a solution of random nonlinear integral equations and we present a numerical example.

Human muscles provide the mechanical energy necessary to set the body in motion. Some muscles, such as those in the lower limbs, provide large forces required to walk or run while others, like those around the wrist, have the dexterity needed to perform complex tasks. Understanding how these muscles function is an integral component of comprehending skeletal motion. Models and simulations of mu...

The analogy between determinantal point processes (DPPs) and free fermionic calculi is well-known. We out that, from the perspective of algebras, Pfaffian (PfPPs) naturally emerge, show that a positive contraction acting on ''doubled'' one-particle space with an additional structure defines unique PfPP. Recently, Olshanski inverted direction fermions to DPPs, proposed scheme construct state qua...

background: accidents are the second reason for mortality and morbidity in iran. among them, brain injuries are the most important damage. clarification of the effects of brain injuries on different body systems will help physicians to prioritize their treatment strategies. in this study, the effect of pure brain trauma on the cardiovascular system and lungs 24 hours post trauma was assessed. m...

Study design: A quasi-experimental study design Background: The motion of the suboccipital region is controlled by several groups smaller and larger muscle group, these might play a role in development cervicogenic headache. Abnormal tone can lead to abnormal movement patterns resulting altered proprioceptive information from mechanoreceptors this region. Thus, will contribute cervical dysfunct...
