The Regulator Problem with Robust Stability [PDF]

open access: yesIFAC Proceedings Volumes, 1995
The system considered is \(\dot x= Ax+ Bu\), \(y= Cx\) where the exosubsystem \(\dot x_2= A_{22} x_2\) has its eigenvalues on the stability boundary \(\text{Re}(s)= 0\). The compensator is \(\dot z= Fz+ Gy\), \(u= Hz+ Jy\). It is supposed that \((A_{11}, B)\) is stabilizable, \((C, A)\) is detectable and that the plant zeros do not coincide with the ...

On Stability for Optimization Problems

open access: yesThe Annals of Probability, 1974
Small perturbations of certain species of optimization problems,--in particular of so-called casino problems with a fixed goal--cause only small perturbations of the optimal strategies.

Initial Value Problems of Semilinear Supdiffusion Equations

open access: yesMathematics, 2020
We consider the existence of a mild solution of supdiffusion equations and obtain some results under some growth and noncompactness conditions of nonlinearity without coefficient restriction; and some new results for Ulam-Hyers-Rassias stability are ...

Some Economic Dynamics Problems for Hybrid Models with Aftereffect

open access: yesMathematics, 2020
In this paper, we consider a class of economic dynamics models in the form of linear functional differential systems with continuous and discrete times (hybrid models) that covers many kinds of dynamic models with aftereffect.

Stability in Obstacle Problems.

open access: yesMATHEMATICA SCANDINAVICA, 1994
This paper concerns obstacle problems relative to a second-order degenerate elliptic operator. Stability properties of the solutions for varying obstacles are stated. Similar results have been (previously) obtained by \textit{H. Attouch} and \textit{C. Picard} [Appl. Anal. 12, 287-306 (1981; Zbl 0479.49008)] and by \textit{G. Dal Maso} [J. Funct. Anal.

Stability for the Lens Rigidity Problem [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2017
Let $g$ be a Riemannian metric for $\mathbf{R}^d$ ($d\geq 3$) which differs from the Euclidean metric only in a smooth and strictly convex bounded domain $M$. The lens rigidity problem is concerned with recovering the metric $g$ inside $M$ from the corresponding lens relation on the boundary $\partial M$.

Quantitative Stability of Optimization Problems with Stochastic Constraints

open access: yesMathematics, 2023
In this paper, we consider optimization problems with stochastic constraints. We derive quantitative stability results for the optimal value function, the optimal solution set and the feasible solution set of optimization models in which the underlying ...

Stability, Periodicity, and Related Problems in Fractional-Order Systems

open access: yesMathematics, 2022
This Special Issue aims to collect new perspectives on the trends in both theory and applications of stability of fractional order continuous and discrete systems, analytical and numerical approaches, and any related problems regarding (but not limited ...

Stability of Solutions to Evolution Problems

open access: yesMathematics, 2013
Large time behavior of solutions to abstract differential equations is studied. The results give sufficient condition for the global existence of a solution to an abstract dynamical system (evolution problem), for this solution to be bounded, and for ...

Visual stability—what is the problem? [PDF]

open access: yesFrontiers in Psychology, 2015
The papers in this volume of Frontiers all relate to 3D vision. What, then, is a paper about visual stability doing among them? I will argue that these topics are really two sides of the same coin: if we are not to be surprised by the changes in images that occur as we move (we see a stable world), we must have some sort of representation of the 3D ...
