The Grassmann-like manifold of centered planes when a surface is described by the centre

open access: yesДифференциальная геометрия многообразий фигур, 2021
We continue to study of the Grassmann-like manifold of -centered planes. A special case is considered when the center de­scribes an -dimensional surface . We will denote this mani­fold by . An analogue of the strong Norden normalization of the manifold

The parameterization method for center manifolds [PDF]

open access: yes, 2019
In this paper, we present a generalization of the parameterization method, introduced by Cabr\'{e}, Fontich and De la Llave, to center manifolds associated to non-hyperbolic fixed points of discrete dynamical systems.

Rigorous justification of Taylor dispersion via center manifolds and hypocoercivity [PDF]

open access: yes, 2018
Taylor diffusion (or dispersion) refers to a phenomenon discovered experimentally by Taylor in the 1950s where a solute dropped into a pipe with a background shear flow experiences diffusion at a rate proportional to 1/ν, which is much faster than what ...

Attraction property of local center-unstable manifolds for differential equations with state-dependent delay

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
In the present paper we consider local center-unstable manifolds at a stationary point for a class of functional differential equations of the form $\dot{x}(t)=f(x_{t})$ under assumptions that are designed for application to differential equations with ...

Closed aspherical manifolds with center [PDF]

open access: yesJournal of Topology, 2013
We show that in all dimensions >7 there are closed aspherical manifolds whose fundamental groups have nontrivial center but do not possess any topological circle actions. This disproves a conjectured converse (proposed by Conner and Raymond) to a classical theorem of Borel.

Local stable manifold of Langevin differential equations with two fractional derivatives

open access: yesAdvances in Difference Equations, 2017
In this paper, we investigate the existence of local center stable manifolds of Langevin differential equations with two Caputo fractional derivatives in the two-dimensional case.

Invariant manifolds around soliton manifolds for the nonlinear Klein-Gordon equation [PDF]

open access: yes, 2011
We construct center-stable and center-unstable manifolds, as well as stable and unstable manifolds, for the nonlinear Klein-Gordon equation with a focusing energy sub-critical nonlinearity, associated with a family of solitary waves which is generated ...

A path integral approach to the Kontsevich quantization formula [PDF]

open access: yes, 1999
We give a quantum field theory interpretation of Kontsevich's deformation quantization formula for Poisson manifolds. We show that it is given by the perturbative expansion of the path integral of a simple topological bosonic open string theory.

Radiation Reaction and Center Manifolds [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2000
Summary: We study the effective dynamics of a mechanical particle coupled to a wave field and subject to the slowly varying potential \(V(\varepsilon q)\) with \(\varepsilon\) small. To lowest order in \(\varepsilon\) the motion of the particle is governed by an effective Hamiltonian.
