On Montessus de Ballore’s theorem for simultaneous Padé-Faber approximants

open access: yesDemonstratio Mathematica, 2018
We consider row sequences of vector valued Padé-Faber approximants (simultaneous Padé-Faber approximants) and prove a Montessus de Ballore type theorem.

On Cheng's eigenvalue comparison theorem

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2008
AbstractWe observe that Cheng's Eigenvalue Comparison Theorem for normal geodesic balls [4] is still valid if we impose bounds on the mean curvature of the distance spheres instead of bounds on the sectional and Ricci curvatures. In this version, there is a weak form of rigidity in case of equality of the eigenvalues.

On a global implicit function theorem for locally Lipschitz maps via nonsmooth critical point theory

open access: yes, 2017
We prove a non-smooth generalization of the global implicit function theorem. More precisely we use the non-smooth local implicit function theorem and the non-smooth critical point theory in order to prove a non-smooth global implicit function theorem ...

A comparison theorem

open access: yesMathematische Annalen, 1986
Let X be any algebraic variety over \({\mathbb{C}}\). Then there is in a natural way associated to X a complex analytic space \(X_{an}\). Also for every coherent algebraic sheaf F on X there is an associated coherent analytic sheaf \(F_{an}\) on \(X_{an}\), and one has comparison maps \(\alpha_ i: H^ i(X,F)\to H^ i(X_{an},F_{an})\) on cohomology.

Generalized nonlinear Picone's identity for the p-Laplacian and its applications

open access: yesElectronic Journal of Differential Equations, 2016
In this article we derive a generalized version of nonlinear Picone's identity for the p-Laplacian. We use this identity to obtain a Hardy-type inequality and a Sturm comparison result.

Representation Theorem for Generators of BSDEs Driven by G-Brownian Motion and Its Applications

open access: yesAbstract and Applied Analysis, 2013
We obtain a representation theorem for the generators of BSDEs driven by G-Brownian motions and then we use the representation theorem to get a converse comparison theorem for G-BSDEs and some equivalent results for nonlinear expectations generated by G ...

An Extension Theorem for Weighted Ricci Curvature on Finsler Manifolds

open access: yesCumhuriyet Science Journal, 2019
Let(M,F) be a forward complete and connected Finsler manifold of dimensional n≥2. In this study, we extend Wan’s extension theorem in Riemannian manifolds to Finsler manifolds by using the weighted Ricci curvatureRicNbounded below.

A Comparison Theorem for Oscillation of the Even-Order Nonlinear Neutral Difference Equation

open access: yesAbstract and Applied Analysis, 2014
A comparison theorem on oscillation behavior is firstly established for a class of even-order nonlinear neutral delay difference equations. By using the obtained comparison theorem, two oscillation criteria are derived for the class of even-order ...

Convergence and stability of stochastic parabolic functional differential equations

open access: yesAdvances in Difference Equations, 2018
The main purpose of this paper is to investigate the convergence and stability of stochastic parabolic functional differential equations. Firstly, a comparison theorem in the context of Lyapunov-like function together with differential inequality is ...
