New features of circular geodesics in Kalb–Ramond gravity: an autonomous dynamical system approach
European Physical Journal C: Particles and FieldsKalb–Ramond gravity is expected to show the signatures of the low energy limit of the Lorentz violating extension of the standard model of particle physics.

On multi-lump solutions to the non-linear Schrodinger equation
Electronic Journal of Differential Equations, 1998 We present a new approach to proving the existence of semi-classical bound states of the non-linear Schrodinger equation which are concentrated near a finite set of non-degenerate critical points of the potential function.

Periodic or homoclinic orbit bifurcated from a heteroclinic loop for high-dimensional systems
Open MathematicsConsider an autonomous ordinary differential equation in Rn{{\mathbb{R}}}^{n}, which has a heteroclinic loop. Assume that the heteroclinic loop consists of two degenerate heteroclinic orbits γ1{\gamma }_{1}, γ2{\gamma }_{2} and two saddle points with ...

Alexandria Engineering JournalIn this paper, the investigation examines the problem of creeping flow of a non-Newtonian couple-stress fluid through a linear porous-walled slit within a Darcy porous material. A method uses similar shapes made by changing coordinates and making complex

On the generic existence of homoclinic points [PDF]
Ergodic Theory and Dynamical Systems, 1987 AbstractThis work is concerned with the generic existence of homoclinic points for area preserving diffeomorphisms of compact orientable surfaces. We give a shorter proof of Pixton's theorem that shows that, Cr-generically, an area preserving diffeomorphism of the two sphere has the property that every hyperbolic periodic point has transverse ...

Homoclinic intersections of symplectic partially hyperbolic systems with 2D center
, 2015 We study some generic properties of partially hyperbolic symplectic systems with 2D center. We prove that $C^r$ generically, every hyperbolic periodic point has a transverse homoclinic intersection for the maps close to a direct/skew product of an Anosov

Bifurcation Analysis of the Dynamics in COVID-19 Transmission through Living and Nonliving Media
Journal of Applied MathematicsTransmission of COVID-19 occurs either through living media, such as interaction with a sufferer, or nonliving objects contaminated with the virus. Recovering sufferers and disinfectant spraying prevent interaction between people and virus become the ...
