Time-varying discrete-time linear systems with bounded rates of variation: Stability analysis and control design
(Pergamon-elsevier Science LtdOxfordInglaterra, 2009)
Boundedness of solutions
(2021-01-01)
This chapter presents the concepts of uniform boundedness, quasiuniform boundedness, and uniform ultimate boundedness in the scenery of generalized ordinary differential equations (ODEs). It includes criteria of uniform ...
Procedimento para detecção de falseamento via amostragem não uniforme
(Universidade Federal de Minas GeraisUFMG, 2015-09-15)
The sampling theorem determines a lower bound for the sampling frequency necessary for the perfect representation of a continuous signal by a countable set of uniformly spaced time samples. If such a bound is not satisfied ...
Bounded solutions of neutral fermions with a screened Coulomb potential
(Elsevier B.V., 2005-11-01)
The intrinsically relativistic problem of a fermion subject to a pseudoscalar screened Coulomb plus a uniform background potential in two-dimensional space-time is mapped into a Sturm-Liouville. This mapping gives rise to ...

Stability of Stochastic Gradient Descent on Nonsmooth Convex Losses
(2020)
Uniform stability is a notion of algorithmic stability that bounds the worst case change in the model output by the algorithm when a single data point in the dataset is replaced. An influential work of Hardt et al. [2016] ...
Examples of homogeneous manifolds with uniformly bounded metric projection
(Unión Matemática Argentina, 2012-11)
Let M be a finite von Neumann algebra with a faithful normal trace τ. Denote by Lp(M)sh the skew-Hermitian part of the non-commutative Lp space associated with (M, τ). Let 1 < p < ∞, z ∈ Lp(M)sh and S be a real closed ...
UNIFORM DISSIPATIVENESS, ROBUST SYNCHRONIZATION AND LOCATION OF THE ATTRACTOR OF PARAMETRIZED NONAUTONOMOUS DISCRETE SYSTEMS
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2011)
In this series of papers, we study issues related to the synchronization of two coupled chaotic discrete systems arising from secured communication. The first part deals with uniform dissipativeness with respect to parameter ...
