On the Nonlinear Stability of Symplectic Integrators [PDF]
BIT Numerical Mathematics, 2004 The paper deals mainly with the problem of achieving stability for symplectic numerical integrators by the mean of studying the topological equivalence of the level sets of the original Hamiltonian and those of the modified Hamiltonian associated to the numerical integrators.

Nonlinear Stability at the Eckhaus Boundary [PDF]
SIAM Journal on Mathematical Analysis, 2018 The real Ginzburg-Landau equation possesses a family of spatially periodic equilibria. If the wave number of an equilibrium is strictly below the so called Eckhaus boundary the equilibrium is known to be spectrally and diffusively stable, i.e., stable w.r.t. small spatially localized perturbations.

Geophysical Research Letters, 2016 Wide compensated vortices are not able to remain circular in idealized two‐layer models unless the ocean depth is assumed to be unrealistically large. Small perturbations on both cyclonic and anticyclonic eddies grow slower if a middle layer with uniform

Stability of Charged Global AdS$_4$ Spacetimes [PDF]
, 2016 We study linear and nonlinear stability of asymptotically AdS$_4$ solutions in Einstein-Maxwell-scalar theory. After summarizing the set of static solutions we first examine thermodynamical stability in the grand canonical ensemble and the phase ...

Novel stability results for traveling wavefronts in an age-structured reaction-diffusion equation
Mathematical Biosciences and Engineering, 2009 For a time-delayed reaction-diffusion equation of age-structuredsingle species population, the linear and nonlinear stability ofthe traveling wavefronts were proved by Gourley [4] andLi-Mei-Wong [8] respectively. The stability results,however, assume the

On the nonlinear stability of a quasi-two-dimensional drift kinetic model for ion temperature gradient turbulence [PDF]
, 2015 We study a quasi-two-dimensional electrostatic drift kinetic system as a model for near-marginal ion temperature gradient (ITG) driven turbulence. A proof is given of the nonlinear stability of this system under conditions of linear stability. This proof

A nonlinear $L^2$-stability analysis for two-species population dynamics with dispersal
Mathematical Biosciences and Engineering, 2005 The nonlinear $L^2$-stability (instability) of the equilibrium statesof two-species population dynamics with dispersal is studied. The obtainedresults are based on (i) the rigorous reduction of the $L^2$-nonlinear stability tothe stability of the zero ...
