A note on linearized stability of Schwarzschild thin-shell wormholes with variable equations of state [PDF]
, 2015 We discuss how the assumption of variable equation of state (EoS) allows the elimination of the instability at equilibrium throat radius $a_0=3M$ featured by previous Schwarzschild thin-shell wormhole models.

The probabilistic real stability radius
IFAC Proceedings Volumes, 1999 Abstract In this paper we study the probabilistic real stability radius , which gives a description of the degradation of the probability of stability beyond the classical real stability radius. The main result of the paper is to determine the probability density function of the singular values of the perturbation matrix ▵.

Effect of eccentricity and inner pipe motion on flow instability for flow through annulus
SN Applied Sciences, 2021 Present work implements the Energy gradient method (EGM) to study the effect of variation in eccentricity, radius ratio and inner pipe movement on the fully developed flow of Newtonian fluid through an annulus for the flow instability.

Minimum mass-radius ratio for charged gravitational objects [PDF]
, 2007 We rigorously prove that for compact charged general relativistic objects there is a lower bound for the mass-radius ratio. This result follows from the same Buchdahl type inequality for charged objects, which has been extensively used for the proof of ...

On one type of stability for multiobjective integer linear programming problem with parameterized optimality [PDF]
Computer Science Journal of Moldova, 2020 A multiobjective problem of integer linear programming with parametric optimality is addressed. The parameterization is introduced by dividing a set of objectives into a family of disjoint subsets, within each Pareto optimality is used to establish ...

Stability of the toroidal magnetic field in rotating stars [PDF]
, 2013 The magnetic field in stellar radiation zones can play an important role in phenomena such as mixing, angular momentum transport, etc. We study the effect of rotation on the stability of a predominantly toroidal magnetic field in the radiation zone.

The Stability Radius of Fredholm Linear Pencils
Journal of Mathematical Analysis and Applications, 2001 Let \(T\) and \(S\) be two bounded linear operators from Banach spaces \(X\) into \(Y\), and suppose that \(T\) is Fredholm and \(\dim N(T-\lambda S)\) is constant in a neighborhood of \(\lambda=0\). Let \(d(T;S)\) be the supremum of all \(r>0\) such that \(\dim N(T-\lambda S)\) and \(codim R(T-\lambda S)\) are constant for all \(\lambda\) with ...
