This Workshop is a regular meeting taking place in Viña del Mar or Valparaíso, Chile, since December 1985, found by Professor Enrique Tirapegui. This Workshop aims to create a stimulating environment for experts from the region and the rest of the world to present and discuss their results with the nonlinear community. Since its beginning, a primary goal of the Workshop has been to promote and facilitate the participation and cross-discipline interaction of young scientists together with more established experts from a wide variety of fields in Nonlinear Science.

Because of the sanitary conditions generated by the pandemic, it is expected that the event will be held in a hybrid way (online and in-person).

Patterns emerging in nonequilibrium systems
  This workshop session has a very special character since it appears on the memory of Professor Enrique Tirapegui (1940-2020); An author of many seminal papers, Enrique Tirapegui completed his Bachelor’s in physics from the University of Chile (1962), Ph.D. in Mathematics and Ph.D. in Theoretical Physics at the University of Paris. He was incorporated as a number member of the Chilean Academy of Sciences, Institute of Chile, in 1984. He was a full professor of the Physics Department of the Faculty of Physical and Mathematical Sciences of the University of Chile (1982-2020). In 1991, he was honored with the Chilean National Prize for his contributions on “the effects of random perturbations experienced by macroscopic systems, and in the formation of spatiotemporal structures in such systems, which are far from thermodynamic equilibrium.” In his distinguished career, Prof. Tirapegui published more than 120 scientific articles in journals with mainstream physics and has trained more than 20 scientists, founding the nonlinear school in Chile. His main scientific efforts were concentrated on the theory of normal forms, description of stochastic processes using path integrals, instabilities in fluids, vortex interaction, and noise-induced robust effect.

  This conference is the oldest one in South America which is strictly devoted to the study of Nonlinear Science. The workshop has been an essential element to develop the discipline in the region. The Proceedings of the first nine sessions have been published regularly with Kluwer Academic Publishers (Holland) in the Series on Nonlinear Phenomena and Complex Systems of the Centro de Física No Lineal y Sistemas Complejos de Santiago (CFNL), a center founded by Prof. Tirapegui. The Proceedings of the 11th session appeared in a select number of the International Journal of Bifurcations and Chaos, and the Proceedings of the 12th session were published in a special issue of the European Journal of Physics D. The Proceedings of the 16th session have been published in the Philosophical Transactions of the Royal Society. The Proceedings of the 17th session have been published in Chaos journal.
