Floquet Stability Analysis of Ott-Grebogi-Yorke and Difference Control [PDF]
, 2008 Stabilization of instable periodic orbits of nonlinear dynamical systems has been a widely explored field theoretically and in applications. The techniques can be grouped in time-continuous control schemes based on Pyragas, and the two Poincar\'e-based ...

Perturbation of singular integral operators with piecewise continuous coefficients
Acta et Commentationes: Ştiinţe Exacte şi ale NaturiiIn the paper it is shown that the property of singular integral operators with piecewise continuous coefficients to be Noetherian is stable with respect to their perturbation with certain non-compact operators. An example is constructed showing that the

Spatially-distributed coverage optimization and control with limited-range interactions [PDF]
, 2004 This paper presents coordination algorithms for groups of mobile agents performing deployment and coverage tasks. As an important modeling constraint, we assume that each mobile agent has a limited sensing/communication radius.

Regularization dependence of the OTOC. Which Lyapunov spectrum is the physical one? [PDF]
JHEP 07 (2019) 107, 2019 We study the contour dependence of the out-of-time-ordered correlation function (OTOC) both in weakly coupled field theory and in the Sachdev-Ye-Kitaev (SYK) model. We show that its value, including its Lyapunov spectrum, depends sensitively on the shape of the complex time contour in generic weakly coupled field theories.

A Unified Approach to High-Gain Adaptive Controllers [PDF]
, 2009 It has been known for some time that proportional output feedback will stabilize MIMO, minimum-phase, linear time-invariant systems if the feedback gain is sufficiently large.

Singular integral operators. The case of an unlimited contour
Journal of Numerical Analysis and Approximation Theory, 2005 Let \(\Gamma\)be a closed or unclosed unlimited contour, a shift \(\alpha(t)\) maps homeomorphicly the contour \(\Gamma\) onto itself with preserving or reversing the direction on \(\Gamma\) and also satisfies the conditions: for some natural \(n\geq2\),

Systematic Stabilization of Constrained Piecewise Affine Systems [PDF]
arXiv, 2022 This paper presents an efficient, offline method to simultaneously synthesize controllers and seek closed-loop Lyapunov functions for constrained piecewise affine systems on triangulated subsets of the admissible states. Triangulation refinements explore a rich class of controllers and Lyapunov functions.

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract Although the concept of thermodynamic entropy due to Clausius dates back to the early 1850s, the mathematical theory of informational entropy was not developed until the pioneering work of Shannon in 1948, the development of principle of maximum entropy (POME) and theorem of concentration by Jaynes in 1957, principle of minimum cross entropy ...

Non-hermitean delocalization in an array of wells with variable-range widths
, 2000 Nonhermitean hamiltonians of convection-diffusion type occur in the description of vortex motion in the presence of a tilted magnetic field as well as in models of driven population dynamics. We study such hamiltonians in the case of rectangular barriers

PDE‐based containment control of linear multi‐agent systems
International Journal of Robust and Nonlinear Control, Volume 35, Issue 3, Page 743-769, February 2025.Abstract This contribution considers the containment control problem for linear multi‐agent systems (MAS) using continuum models in form of linear parabolic PDEs. For this, a networked controller is designed, that ensures the asymptotic convergence of finite‐dimensional agents into a containment area specified by dynamic leaders. This problem is traced
