Linear Stability of a Combined Convective Flow in an Annulus

Fluids, 2023
Linear stability analysis of a combined convective flow in an annulus is performed in the paper. The base flow is generated by two factors: (a) different constant wall temperatures and (b) heat release as a result of a chemical reaction that takes place ...

Numerical methods for solving nonlinear Volterra integro-differential equations based on Hermite–Birkhoff interpolation [PDF]

Iranian Journal of Numerical Analysis and Optimization, 2020
We introduce a new family of multivalue and multistage methods based on Hermite–Birkhoff interpolation for solving nonlinear Volterra integro differential equations.

World-sheet Stability of (0,2) Linear Sigma Models [PDF]

, 2003
We argue that two-dimensional (0,2) gauged linear sigma models are not destabilized by instanton generated world-sheet superpotentials. We construct several examples where we show this to be true.

Analysis Modulation Instability and Parametric Effect on Soliton Solutions for M-Fractional Landau–Ginzburg–Higgs (LGH) Equation Through Two Analytic Methods

Fractal and Fractional
This manuscript studies the M-fractional Landau–Ginzburg–Higgs (M-fLGH) equation in comprehending superconductivity and drift cyclotron waves in radially inhomogeneous plasmas, especially for coherent ion cyclotron wave propagation, aiming to explore the

Dynamics of self-sustained asynchronous-irregular activity in random networks of spiking neurons with strong synapses

Frontiers in Computational Neuroscience, 2014
Random networks of integrate-and-fire neurons with strong current-based synapses can, unlike previously believed, assume stable states of sustained asynchronous and irregular firing, even without external random background or pacemaker neurons.We analyze

Linear stability in billiards with potential

, 1996
A general formula for the linearized Poincar\'e map of a billiard with a potential is derived. The stability of periodic orbits is given by the trace of a product of matrices describing the piecewise free motion between reflections and the contributions ...

Stability of non-linear integrable accelerator

, 2011
The stability of non-linear Integrable Optics Test Accelerator (IOTA) model was tested. The area of the stable region in transverse coordinates and the maximum attainable tune spread were found as a function of non-linear lens strength.

Stability properties of the collective stationary motion of self-propelling particles with conservative kinematic constraints [PDF]

, 2006
In our previous papers we proposed a continuum model for the dynamics of the systems of self-propelling particles with conservative kinematic constraints on the velocities. We have determined a class of stationary solutions of this hydrodynamic model and

On linear stability and syzygy stability

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 2022
AbstractIn previous works, the authors investigated the relationships between linear stability of a generated linear series |V| on a curve C, and slope stability of the syzygy vector bundle $$M_{V,L} := \ker (V \otimes \mathcal {O}_C \rightarrow L)$$ M

Dynamical stability criterion for inhomogeneous quasi-stationary states in long-range systems

, 2010
We derive a necessary and sufficient condition of linear dynamical stability for inhomogeneous Vlasov stationary states of the Hamiltonian Mean Field (HMF) model.
