The Symposium is an extraordinary opportunity for scholars to meet and June 30-July 7, 2004.

The participants cover a wide range of Hyatt Regency Orlando (Near Walt Disney World Resort) under the auspices of the expertise, from pure theoreticians to people primarily oriented toward applications. International Federation of Nonlinear Analysts (IFNA). It is a great honour to held this Symposium under the auspice of the IFNA as an Invited session by GOC WCNA 2004. A significant achievement of the Symposium is expected to be extensive in-depth At the beginning there is a question: What is the integrity of a dynamical discussion on a variety of topics ranging from highly theoretical questions to system? One or more answers,as well as corresponding definitions of the used practical engineering applications. notions, are needed. Further questions also appear in correlations with the first The main conclusion that can be drawn from a total of 16 abstracts of lectures basic question. presented in this Booklet is that nonlinear mechanics keeps on deserving a great Firstly, let us make some remarks as regards the word source integrity. The scientific interst as far as both methodology and applicability are concerned. word integrity originates from the Latin word integritas and has the following We can write: "So what is new in nonlinear dynamics and Mechanics today? meanings: inviolable, untouched state, completeness, intactness, on the whole, The initial scope of applications in solid mechanics has broadened to cover material purity of spirit, chastity, innocence. processing, inelasticity and fracture mechanics. In rigid body dynamics, more Also the Latin word integrum has the following meaning: untouched totality complex systems such as vehicles, robotics and controlled machines have (entirety). The Latin expression in integrum has the following meaning: return in come into the framework of nonlinear dynamics. On the mathematical side of the previous state, or in the previous position. nonlinear dynamics, it is now recognized that spatio-temporal problems, hysteretic We have enough reason to feel ourselves gratified with the content of the invited lectures and time delay problems are new frontiers in this field. Also the term ‘complexity’ of this Minisymposium INTEGRITY OF DYNAMICAL SYSTEMS, which witness how the has been added to the lexicon of the chaos theory to describe the dynamics of many Minysimposium has received active support and extensive attention within academic and interacting sub-systems which can exhibit self-organization and evolution. engineering communities. This shows that the subject of Integrity of Dynamical Systems is Complexity analysis has gained a foothold in biological and some social sciences both a basic issue of interest in applied mathematics and a final aim in nonlinear mechanics, as well as in fluid and chemical physics. It remains to be seen what impact it will with a prosperous vitality and a remarkable progress in recent years. have in applied mechanics and engineering. Vitality and attraction of a research field originate from its social demand. We can point Here, I would like to express my heartfelt thanks to all members of the out that twenty years ago, with the rapid development of economy, science and technology scientific Committee, and also to the participants, for their engagement in people have been facing with the challenge of many nonlinear problems. This situation provides ample opportunities for addressing the topic of the Integrity of Dynamical Systems. organizing the Symposium, including the preparation of manuscripts which will be As a matter of fact, I have been sincerely pleased with my perusing of the content of published in the WCNA IFNA post congress publications (journal).

Finally, on behalf of my colleagues in Serbia and Montenegro, I would like to I enjoyed pleasant honor and cooperation with the members of the chairmen session wish all the Invited participants to the Symposium a warm welcome and thanks.
