The first part deals with uniform dissipativeness with respect to parameter variation via the Liapunov direct method. We obtain uniform estimates of the global attractor for a general discrete nonautonomous system, that yields a uniform invariance principle in the autonomous case. The Liapunov function is allowed to have positive derivative along solutions of the system inside a bounded set, and this reduces substantially the difficulty of constructing a Liapunov function for a given system. In particular, we develop an approach that incorporates the classical Lagrange multiplier into the Liapunov function method to naturally extend those Liapunov functions from continuous dynamical system to their discretizations, so that the corresponding uniform dispativeness results are valid when the step size of the discretization is small. Applications to the discretized Lorenz system and the discretization of a time-periodic chaotic system are given to illustrate the general results. We also show how to obtain uniform estimation of attractors for parametrized linear stable systems with nonlinear perturbation. <\/jats:p>","DOI":"10.1142\/s0218127411028568","type":"journal-article","created":{"date-parts":[[2011,3,4]],"date-time":"2011-03-04T10:42:47Z","timestamp":1299235367000},"page":"513-526","source":"Crossref","is-referenced-by-count":4,"title":["UNIFORM DISSIPATIVENESS, ROBUST SYNCHRONIZATION AND LOCATION OF THE ATTRACTOR OF PARAMETRIZED NONAUTONOMOUS DISCRETE SYSTEMS"],"prefix":"10.1142","volume":"21","author":[{"given":"HILDEBRANDO M.","family":"RODRIGUES","sequence":"first","affiliation":[{"name":"Departamento de Matem\u00e1tica Aplicada e Estat\u00edstica, Instituto de Ci\u00eancias Matem\u00e1ticas e de Computa\u00e7\u00e3o, Universidade de S\u00e3o Paulo, Caixa Postal 668, 13560-970, S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JIANHONG","family":"WU","sequence":"additional","affiliation":[{"name":"Laboratory for Industrial and Applied Mathematics, Department of Mathematics and Statistics, York University, Toronto, Canad\u00e1 M3J1P3, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LU\u00cdS R.
