Frequency‐Domain Analysis of External Signal Propagation Through Sliding Mode Control Systems With Dynamic Actuators

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The importance of frequency domain methods in analysis and design of sliding mode (SM) control systems is mostly associated with chattering, where the advantages of these methods over state‐space and Lyapunov's methods are quite obvious.

Approximation of analytic functions satisfying a Lipschitz condition. [PDF]

open access: yesMichigan Mathematical Journal, 1978
Let \(\lambda_\alpha\), \(0 0\) there exists a function \(f_\varepsilon\in \lambda_\alpha\) such that (i) the inner factors of \(f\) and \(f_\varepsilon\) coincide, (ii) \(\Vert f - f_\varepsilon\Vert < \varepsilon\), (iii) \(\vert f_\varepsilon(z)\vert = O(\operatorname{dist}^M(z,E))\) as \(\operatorname{dist}(z,E)\to 0\). The proof is fairly long and

Initial State Privacy of Nonlinear Systems on Riemannian Manifolds

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.

Letter Written by George Lipschitz to the Bryant College Service Club Dated December 29, 1942

open access: yes, 1942
[Transcription begins] 54th Medical Battalion Camp Edwards, Mass. December 29, 1942. Dear Friends, Thanks so much for the Christmas gift. Honestly, it did help to make my holiday complete. The package arrived in good condition on Christmas Day.

Invariance of regularity conditions under definable, locally Lipschitz, weakly bi-Lipschitz mappings

open access: yes, 2010
We describe the notion of a weakly Lipschitz mapping on a Cq stratification. We also distinguish a class of regularity conditions that are in some sense invariant under definable, locally Lipschitz and weakly bi-Lipschitz homeomorphisms.

Vertical Deformation Mapping: Steering Optimiser Toward Flat Minima

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Standard deep learning optimisation is typically conducted on shape‐fixed loss surfaces. However, shape‐fixed loss surfaces may impede optimisers from reaching flat regions closely associated with strong generalisation. In this work, we propose a new paradigm named deformation mapping to deform the loss surface during optimisation.

A measure theoretic approach to Lipschitz regularity and its Haar type wavelet analysis

open access: yesMathematical Modelling and Analysis
The $\alpha$−Lipschitz character of a time series or an image summarizes, in the single parameter α, some persistence properties of the original function modeling the given signal.

Sensitivity analysis for HJB equations with an application to a coupled backward-forward system

open access: yes, 2013
In this paper, we analyse the dependence of the solution of Hamilton-Jacobi-Bellman equations on a functional parameter. This sensitivity analysis not only has the interest on its own, but also is important for the mean field games methodology, namely for

Convergence behaviour of inexact Newton methods under weak Lipschitz condition

open access: yes, 2006
Under weak Lipschitz condition, local convergence properties of inexact Newton methods and Newton-like methods for systems of nonlinear equations are established in an arbitrary vector norm.
