On oscillation of solutions of scalar delay differential equation in critical case
Electronic Journal of Qualitative Theory of Differential Equations, 2022 In this paper we study the oscillation problem for the known scalar delay differential equation. We assume that the coefficients of this equation have an oscillatory behaviour with an amplitude of oscillation tending to zero at infinity.

Dynamical system analysis of a Dirac-Born-Infeld model: a center manifold perspective [PDF]
General Relativity and Gravitation, 2019 In this paper we present the cosmological dynamics of a perfect fluid and the Dark Energy component of the Universe, where our model of the dark energy is the string-theoritic Dirac-Born-Infeld (DBI) model.

Time dependent center manifold in PDEs
Discrete and Continuous Dynamical Systems. Series A, 2020 We consider externally forced equations in an evolution form. Mathematically, these are skew systems driven by a finite dimensional dynamical system. Two very common cases included in our treatment are quasi-periodic forcing and forcing by a stochastic ...

Greedy Kernel Methods for Center Manifold Approximation [PDF]
, 2018 For certain dynamical systems it is possible to significantly simplify the study of stability by means of the center manifold theory. This theory allows to isolate the complicated asymptotic behavior of the system close to a non-hyperbolic equilibrium ...

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

On the asymptotic stability of small nonlinear Dirac standing waves in a resonant case [PDF]
, 2007 We study the behavior of perturbations of small nonlinear Dirac standing waves. We assume that the linear Dirac operator of reference $H=D_m+V$ has only two double eigenvalues and that degeneracies are due to a symmetry of $H$ (theorem of Kramers).
