Complementarity and stability conditions

open access: yesPhysics Letters B, 2017
We discuss the issue of complementarity between the confining phase and the Higgs phase for gauge theories in which there are no light particles below the scale of confinement or spontaneous symmetry breaking.

Kuhn-Tucker-based stability conditions for systems with saturation [PDF]

open access: yes, 2001
This paper presents a new approach to deriving stability conditions for continuous-time linear systems interconnected with a saturation. The method presented can be extended to handle a dead-zone, or in general, nonlinearities in the form of piecewise ...

Stability of SARS‐CoV‐2 and other coronaviruses in the environment and on common touch surfaces and the influence of climatic conditions: A review

open access: yesTransboundary and Emerging Diseases, 2020
Although the unprecedented efforts the world has been taking to control the spread of the human coronavirus disease (COVID‐19) and its causative aetiology [severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2)], the number of confirmed cases has ...

Improving foam stability and lautering conditions

open access: yesKvasný průmysl, 2020
How to increase foam stability without adding foam stabilizers? As we published earlier, there was more than a sufficient amount of foam stabilizing substances in beer, but these must not be pushed out of the beer surface by foam negative substances ...

Stability conditions on curves

open access: yes, 2007
We study some examples of Bridgeland-Douglas stability conditions on triangulated categories. From one side we give a complete description of the stability manifolds for smooth projective curves of positive genus.

Nonautonomous partial functional differential equations; existence and regularity

open access: yesNonautonomous Dynamical Systems, 2017
The aim of this work is to establish several results on the existence and regularity of solutions for some nondensely nonautonomous partial functional differential equations with finite delay in a Banach space.

Equivalence of several stability conditions for switched linear systems with dwell time

open access: yesInternational Journal of Robust and Nonlinear Control, 2018
In this paper, several equivalent stability conditions for switched linear systems with dwell time are presented. Both continuous‐time and discrete‐time cases are considered. For the continuous‐time case, the conditions that are convex in system matrices
