We formulate and prove a new criterion for stability of e–processes introduced by A. Lasota and T. Szarek [J. Differential Equations 231 (2006), 513–533]. In particular we prove that that any e–proces...
Stability of symmetric spaces of noncompact type under Ricci flow
symmetric spaces noncompact type under Ricci flow
2010/11/23
In this paper we establish stability results for symmetric spaces of noncompact type under Ricci flow, i.e. we will show that any small perturbation of the symmetric metric is flown back to the origin...
Nowhere dense graph classes, stability, and the independence property
Nowhere dense graph classes the independence property
2010/11/23
A class of graphs is nowhere dense if for every integer r there is a finite upper bound on the size of cliques that occur as (topological) r-minors. We observe that this tameness notion from algorith...
Stability of the solution to inverse obstacle scattering problem
inverse obstacle scattering problem math
2010/11/1
It is proved that if the scattering amplitudes at a fixed wavenumber for two obstacles from a certain large class of obstacles differ a little, than the obstacles differ a little. Error estimate is g...
Efficient numerical stability analysis of detonation waves in ZND
Efficient numerical stability analysis detonation waves in ZND
2010/11/9
As described in the classic works of Lee--Stewart and Short--Stewart, the numerical evaluation of linear stability of planar detonation waves is a computationally intensive problem of considerable int...
In the framework of the PDE's algebraic topology, previously introduced by A. Pr\'astaro, {\em exotic $n$-d'Alembert PDE's} are considered. These are $n$-d'Alembert PDE's, $(d'A)_n$, admitting Cauchy...
We consider stability theory for Polish spaces and more generally for definable structures. We succeed to prove existence of indiscernibles under reasonable conditions.
On the asymptotic stability of a rational multi-parameter first order difference equation
the asymptotic stability rational multi-parameter
2010/11/22
In this part we study the dynamics of the following rational multi-parameter first order difference equation x_{n+1} =(ax_{n}^3+ bx_{n}^2+cx_{n} + d)/x_{n}^3, x_{0}\in R^{+} where the parameters a, b...
The Stability and Dynamics of Localized Spot Patterns in the Two-Dimensional Gray-Scott Model

2010/12/15
The dynamics and stability of multi-spot patterns to the Gray-Scott (GS) reaction-diffusion model in a two-dimensional domain is studied in the singularly perturbed limit of small diffusivity " of one...
Stability and Bifurcation Analysis of Coupled Fitzhugh-Nagumo Oscillators

2010/4/1
Neurons are the central biological objects in understanding how the brain works. The famous Hodgkin-Huxley model, which describes how action potentials of a neuron are initiated and propagated, consis...
Stability Criteria of 3D Inviscid Shears
3D Inviscid Shears laminar shear plane Couette flow
2010/4/8
The classical plane Couette flow, plane Poiseuille flow, and pipe Poiseuille flow share some universal 3D steady coherent structure in the form of "streak-roll-critical layer". As the Reynolds number ...
STABILITY PROBLEM FOR JENSEN-TYPE FUNCTIONAL EQUATIONS OF CUBIC MAPPINGS
Jensen equation Hyers--Ulam--Rassias stability cubic mapping
2007/12/11
In this paper, we establish the general solution and the generalized Hyers--Ulam--Rassias stability problem for a cubic Jensen-type functional equation, \begin{eqnarray*} 4f\Big(\frac{3x+y}{4}\Big)+4f...
AN EXTENSION OF THE BINOMIAL THEOREM WITH APPLICATION TO STABILITY THEORY
Routh-Hurwitz Stability Schur-Cohn Stability Stability Theory Control Theory
2010/3/17
We show how it is possible to put different stability types such as Routh-Hurwitz and Schur-Cohn on common grounds by establishing direct links between them. In the process, we obtain natural and eleg...
