Abstract This paper investigates the problem of observer‐based sliding mode control (SMC) of stochastic uncertain Markov jump systems using dual‐driven event‐triggered mechanism (ETM). The ETM is implemented not only in the system output to the observer channel but also in the feedback channel, forming a dual ETM, which can effectively reduce ...

Effects of small spatial variation of the reproduction rate in a two species competition model
Of concern is the effect of a small spatially inhomogeneous perturbation of the reproduction rate of the first species in a two-species Lotka-Volterra competition-diffusion problem with spatially homogeneous reaction terms.

Abstract This paper focuses on the issue of adaptive event‐triggered containment control for Markov jump multi‐agent systems characterized by hidden Markov jump parameters. The central objective is to design an output‐feedback controller for the Markov jump multi‐agent system by using an adaptive event‐triggered technique that not only ensures the ...

Threshold Effects for the Generalized Friedrichs Model with the Perturbation of Rank One
A family Hμ(p), μ>0, p∈𝕋2 of the Friedrichs models with the perturbation of rank one, associated to a system of two particles, moving on the two-dimensional lattice ℤ2 is considered. The existence or absence of the unique eigenvalue of the operator Hμ(p)

Eigenvalue spectrum of the spheroidal harmonics: A uniform asymptotic analysis
The spheroidal harmonics Slm(θ;c) have attracted the attention of both physicists and mathematicians over the years. These special functions play a central role in the mathematical description of diverse physical phenomena, including black-hole ...

Eigenvalue problems for nonsmoothly perturbed domains
Let \(\Omega_ 0\), \(D\subset\mathbb{R}^ N\) be bounded, connected and smooth domains and \(R\) a connected set such that there exist \(\alpha,\beta\) satisfying \[ \{(x,y)\in\mathbb{R}\times\mathbb{R}^{N-1}: | x|

Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize
