Weak inequalities for maximal functions in Orlicz–Lorentz spaces and applications
(Academic Press Inc Elsevier Science, 2010-02)
Let 00, denote a net of intervals of the form (x-epsilon,x+epsilon) subset [0,alpha). Let f^{epsilon}(x) be any best constant approximation of f in Lambda_{w,phi´} on B(x,epsilon). Weak inequalities for maximal functions ...

Global symmetric approximation of frames
(Springer, 2019-08)
We solve the problem of best approximation by Parseval frames to an arbitrary frame in a subspace of an infinite dimensional Hilbert space. We explicitly describe all the solutions and we give a criterion for uniqueness. ...

Esta tese tem o propósito de apresentar um novo método eficiente para a aproximação clássica pelos mínimos quadrados para grande quantidade de dados, desenvolvido e implementado em softwares que funcionam com suporte à ...
Moment-closure approximations for discrete adaptive networks
(Elsevier Science, 2014-01)
Moment-closure approximations are an important tool in the analysis of the dynamics on both static and adaptive networks. Here, we provide a broad survey over different approximation schemes by applying each of them to the ...
Approximation and parameterized algorithms for geometric independent set with shrinking
(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)
Consider the Maximum Weight Independent Setproblem for rectangles: given a family ofweighted axis-parallel rectangles in the plane, find a maximum-weight subset of non-overlappingrectangles. The problem is notoriously hard ...
