In this paper, we prove the existence and uniqueness of fixed points for cyclic (α,β)-admissible type F-contraction and F−weak contraction under the setting of modular spaces, where the modular is convex and satisfying the ∆2-condition. Later, we prove some periodic point results for self-mappings on a modular space. We also give some examples to s...

In this article we develop convergence theory for a general class of adaptive approximation algorithms for abstract nonlinear operator equations on Banach spaces, and then use the theory to obtain convergence results for practical adaptive finite element methods (AFEM) applied to several classes of nonlinear elliptic equations. In the first part of the paper, we develop a weak-* convergence fra...

Certain constraints that should be interpreted as deenitions or quasi-deenitions can cause prediction problems for logics of action. Standard ways to avoid them rely on notions of priority in the minimization of uent change. We ooer an alternative approach based on belief revision. Revision is performed on the reduct of the system theory after isolating deenitions, and the revised theory is the...

Certain constraints that are interpretable as definitions or quasi-definitions cause prediction problems for logics of action. Standard ways to avoid them rely on notions of priority in the minimization of fluent change. We offer an alternative approach based on belief revision. Revision is performed on the reduct of the system theory after isolating definitions, and the revised theory is then ...

Abstract Introduction: Pregnancy predisposes the emergence of pelvic floor dysfunctions (PFD), postpartum being opportune moment to assess these muscles. Objective: To investigate effect instructions and verbal feedback on contraction capacity muscles (PFM) in women. Methods: Quasi-experimental study with 109 women immediate vaginal at a reference maternity hospital Fortaleza, Ceará state, Braz...

The aim of this paper is to prove some common fixed point theorems for four  mappings satisfying $(psi,varphi)$-weak contractions involving rational expressions in ordered partial metric spaces. Our results extend, generalize and improve some well-known results in the literature. Also, we give two examples to illustrate our results.

In 2009, Ilić and Rakoc̆ević proved that quasi-contraction maps on normal cone metric spaces have a unique fixed point (Ilić and Rakoc̆ević, 2009 [6]). Then, Kadelburg, Radenović and Rakoc̆ević generalized their results by considering an additional assumption (Kadelburg et al., 2009 [7]). Also, they proved that quasi-contraction maps on cone metric spaces have the property (P) whenever λ ∈ (0, 2 )...
