Finite-dimensional complex manifolds on commutative Banach algebras and continuous families of compact complex manifolds [PDF]

open access: greenComplex Manifolds, 2019
Let Γ(M) be the set of all global continuous cross sections of a continuous family M of compact complex manifolds on a compact Hausdorff space X. In this paper, we introduce a C(X)-manifold structure on Γ(M).

On hypersurfaces in a locally affine Riemannian Banach manifold [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2002
We prove that an essential hypersurface of second order in an infinite dimensional locally affine Riemannian Banach manifold is a Riemannian manifold of constant nonzero curvature.

On complex Banach manifolds similar to Stein manifolds [PDF]

open access: yesComptes Rendus. Mathématique, 2010
We give an abstract definition, similar to the axioms of a Stein manifold, of a class of complex Banach manifolds in such a way that a manifold belongs to the class if and only if it is biholomorphic to a closed split complex Banach submanifold of a ...

Chaos and shadowing around a homoclinic tube [PDF]

open access: yesAbstract and Applied Analysis, 2003
Let F be a C3 diffeomorphism on a Banach space B. F has a homoclinic tube asymptotic to an invariant manifold. Around the homoclinic tube, Bernoulli shift dynamics of submanifolds is established through a shadowing lemma. This work removes an uncheckable

On Sussmann theorem for orbits of sets of vector fields on Banach manifolds [PDF]

open access: bronze, 2011
The purpose of this paper is to give some generalizations, in the context of Banach mani- folds, of Sussmann's results about the orbits of families of vector fields ([Su]).

On hypersurfaces in a locally affine Riemannian Banach manifold II [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2004
In our previous work (2002), we proved that an essential second-order hypersurface in an infinite-dimensional locally affine Riemannian Banach manifold is a Riemannian manifold of constant nonzero curvature.

Viscosity method for hierarchical variational inequalities and variational inclusions on Hadamard manifolds

open access: yesJournal of Inequalities and Applications, 2021
This article aims to introduce and analyze the viscosity method for hierarchical variational inequalities involving a ϕ-contraction mapping defined over a common solution set of variational inclusion and fixed points of a nonexpansive mapping on Hadamard

Reduction principle at work

open access: yesNonautonomous Dynamical Systems, 2021
The purpose of this informal paper is three-fold: First, filling a gap in the literature, we provide a (necessary and sufficient) principle of linearized stability for nonautonomous difference equations in Banach spaces based on the dichotomy spectrum ...

A construction of a nonparametric quantum information manifold [PDF]

open access: yes, 2005
We present a construction of a Banach manifold on the set of faithful normal states of a von Neumann algebra, where the underlying Banach space is a quantum analogue of an Orlicz space.

Stability and Persistence of Synchronization in a System with a Diffusive-Time-Lag Coupling

open access: yesSultan Qaboos University Journal for Science, 2008
We study synchronization in the framework of invariant manifold theory for systems with a time lag.  Normal hyperbolicity and its persistence in infinite dimensional dynamical systems in Banach spaces is applied to give general results on synchronization
