Hyperstability of the Jensen functional equation

Acta Mathematica Hungarica, 2013
\textit{S.-M. Jung}, \textit{M. S. Moslehian} and \textit{P. K. Sahoo} [J. Math. Inequal. 4, No. 2, 191--206 (2010; Zbl 1219.39016)] investigated the conditional stability of the generalized Jensen functional equation \(f(ax+by)=af(x)+bf(y)\). Based on a fixed point method, the authors of the present paper consider the hyperstability problem of the ...

Rigidity of hyperstable complexes

Archiv der Mathematik, 2008
A module J over a ring \(\bigwedge\) is said to be hyperstable when \(J \cong J \oplus {\bigwedge}^{\infty}\). Over a module M for which Ext\(^{n+1}(M, \bigwedge) = 0\) we show that the projective n-stems \({\mathcal{P}}\) for which \(\pi_n({\mathcal{P}})\) is hyperstable constitute a single homotopy type.

Bissecododecahedraenes, Unusual Hyperstable Olefins

Angewandte Chemie International Edition in English, 1987
As an alternative to the catalytic procedure,"' directed multistep pagodane-dodecahedrane transformations (routes A and/or B/C in Ref. [2]) are a current goal: for example, via the intermediates 2-5 (Fig. 1 ) in the case of the basic skeletons 116. At intermediate 5 , this route converges with Puquette's dodecahedrane synthesis, which was recently ...

Hyperstable Theories*

1996
Abstract Lascar rank is localized to invariant families of types, and some of its properties are proven. Furthermore, the regular type technology is extended to certain stable theories. This is applied to prove Lachlan’s conjecture for those theories, and derive further structural properties.

On the hyperstability of time-varying blocks

IEEE Transactions on Automatic Control, 1970
The hyperstability of linear time-varying discrete blocks is studied. Sufficient conditions for hyperstability are obtained for special classes of multiple and simple blocks.

On hyperstability of the biadditive functional equation

Acta Mathematica Scientia, 2017
Abstract We present results on approximate solutions to the biadditive equation f ( x + y , z - w ) + f ( x - y , z + w ) = 2 f ( x , z ) - 2 f ( y , w ) on a restricted domain. The proof is based on a quite recent fixed point theorem in some function spaces.

ASYMPTOTIC HYPERSTABILITY OF A CLASS OF NEURAL NETWORKS

International Journal of Neural Systems, 1999
This paper is concerned with the asymptotic hyperstability of recurrent neural networks. We derive based on the stability results necessary and sufficient conditions for the network parameters. The results we achieve are more general than those based on Lyapunov methods, since they provide milder constraints on the connection weights than the ...

The hyperstability approach to VSCS design

1990
A systematic approach to the design of VSC systems has been given. Using the hyperstability theory, the stability of the global system has been established and the existence of the sliding modes. Simple control laws can be used and high speed of response is obtainable by forcing the system with maximum allowable signals, e.g.
