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.

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 Open Scattering Channels for Manifolds with Ends [PDF]
, 2012 In the framework of time-dependent geometric scattering theory, we study the existence and completeness of the wave operators for perturbations of the Riemannian metric for the Laplacian on a complete manifold of dimension $n$.

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 ...

Stability Analysis of Efficient Portfolios in a Discrete Variant of Multicriteria Investment Problem with Savage's Risk Criteria [PDF]
Computer Science Journal of Moldova, 2017 We consider a multicriteria discrete variant of investment portfolio optimization problem with Savage's risk criteria. Three combinations of norms in problem parameter spaces are considered.

Stability radius of second order linear structured differential inclusions
Electronic Journal of Qualitative Theory of Differential Equations, 2015 For arbitrary second order square matrices $A, B, C$; $A$ Hurwitz stable, the minimum positive value $R$ for which the differential inclusion $$\dot{x}\in F_{R}(x):=\{(A+B\Delta C)x, \ \Delta \in \mathbb{R}^{2\times 2},\ \|\Delta \| \le R \}$$ fails to ...

Measure of stability of a Pareto optimal solution to a vector integer programming problem with fixed surcharges in the l1 and l∞ metrics [PDF]
Computer Science Journal of Moldova, 2005 In this paper we consider a vector integer programming problem with Pareto principle of optimality for the case where partial criteria belong to the class of separable piecewise linear functions. The limit level of the initial data's perturbations in the
