The Homoclinic Orbits in the Liénard Plane

open access: yesJournal of Mathematical Analysis and Applications, 1995
In reply to a question, posed by Roberto Conti, concerning the stability properties of the origin to a pseudolinear system in \(\mathbb{R}^ 2\), the situation is clarified for the well-known Liénard system. The notion of the maximal elliptic sector is shown to play an important role with respect to a zero solution to be a positive global (weak ...

Existence and Stability for Traveling Waves of Fourth‐Order Semilinear Wave and Schrödinger Equations

open access: yesStudies in Applied Mathematics, Volume 156, Issue 4, April 2026.
ABSTRACT We investigate the existence and spectral stability of traveling wave solutions for a class of fourth‐order semilinear wave equations, commonly referred to as beam equations. Using variational methods based on a constrained maximization problem, we establish the existence of smooth, exponentially decaying traveling wave profiles for wavespeeds

Homoclinic orbits and Lie rotated vector fields

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Based on the definition of Lie rotated vector fields in the plane, this paper gives the property of homoclinic orbit as parameter is changed and the singular points are fixed on Lie rotated vector fields.

Spatial dynamics in the family of sixth-order differential equations from the theory of partial formation [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
Topic of the paper. Bounded stationary (i.e. independent in time) spatially one-dimensional solutions of a quasilinear parabolic PDE are studied on the whole real line.

Dynamical behavior of a parametrized family of one-dimensional maps

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
The connection of these maps to homoclinic loops acts like an amplifier of the map behavior, and makes it interesting also in the case where all map orbits approach zero (but in many possible ways).

A Numerical Bifurcation Function for Homoclinic Orbits

open access: yesSIAM Journal on Numerical Analysis, 1998
Summary: The authors present a numerical method to locate periodic orbits near homoclinic orbits. Using a method of [\textit{X.-B. Lin}, Proc. R. Soc. Edinb., Ser. A 116, 295-325 (1990; Zbl 0714.34070)] and solutions of the adjoint variational equation, one gets a bifurcation function for periodic orbits, whose periods are asymptotic to infinity on ...

Multiple front and pulse solutions in spatially periodic systems

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract In this paper, we develop a comprehensive mathematical toolbox for the construction and spectral stability analysis of stationary multiple front and pulse solutions to general semilinear evolution problems on the real line with spatially periodic coefficients.

Multiple bursting patterns in lateral habenula neurons: Experiments and computational model

open access: yesThe Journal of Physiology, Volume 604, Issue 8, Page 3396-3412, 15 April 2026.
Abstract figure legend LHb neurons display a variety of bursting patterns, as well as being silent or displaying a tonic or irregular firing pattern. In a set of patch‐clamp experiments in ex vivo mouse lateral habenula (LHb), we were able to record from a number of cells showing characteristic bursts of a few distinguishable types.

Bifurcations of Nontwisted Heteroclinic Loop with Resonant Eigenvalues

open access: yesThe Scientific World Journal, 2014
By using the foundational solutions of the linear variational equation of the unperturbed system along the heteroclinic orbits to establish the local coordinate systems in the small tubular neighborhoods of the heteroclinic orbits, we study the ...

Manipulation of breather waves with split-dispersion cascaded fibers

open access: yesNew Journal of Physics, 2022
A stabilization scheme is proposed for the dynamics of breather waves induced by the coherent-seed modulation instability based on manipulation of phase-space trajectory. Theoretical and numerical analysis show that carefully dispersion- and nonlinearity-
