A nonlinear singular perturbation problem

open access: yesAsymptotic Analysis, 2006
Let F(u ε )+ε(u ε −w)=0 (1) where F is a nonlinear operator in a Hilbert space H, w∈H is an element, and ε>0 is a parameter. Assume that F(y)=0, and F′(y) is not a boundedly invertible operator.

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

The motion of point particles in curved spacetime [PDF]

open access: yes, 2011
This review is concerned with the motion of a point scalar charge, a point electric charge, and a point mass in a specified background spacetime. In each of the three cases the particle produces a field that behaves as outgoing radiation in the wave zone,

Eventually competitive systems generated by perturbations

open access: yesElectronic Journal of Differential Equations, 2019
A dynamical system is called eventually competitive if it preserves a partial order in backward time only after some reasonable initial transient. We show that both regular and singular perturbations of a competitive irreducible vector field are at ...
