Welington de Melo (Guape, 1946 - Rio de Janeiro, 2016) was a brazilian mathematician whose contributions were deeply connected with Smale and Palis school of dynamical systems. In particular the classification of smooth dynamical systems and the study of its generic properties are recurrent topics in his work. This book collected some of his most significant contributions, from his early work on structural stability of diffeomorphisms in the 1970's to his groundbreaking results on one-dimensional dynamics. Indeed his interest in one-dimensional dynamics is a clear distinction from early influences. An effervescent work in discrete dynamics on the interval and the circle started in the 1970s. It was soon realized that those systems have surprisingly rich dynamics. But, at the same time, an impressive set of tools were developed to study them. There are two main sets of tools. Real methods such as bounded distortion control via Schwarzian derivative and later cross-ratio estimates allows one to understand some of its features. However, often complex methods, with deep connections with Teichmuller theory, are necessary to obtain some of the most striking results. This is especially true in renormalization theory, a theme Welington was very fond of, and that appears prominently in his collected works. Welington played an important role in the development on both fronts, and this book is a testament of his influence in the field which resonates to this day.

A continuation of Silvana Editoriale's Posters series, this volume presents the most significant examples of advertising graphics produced by Italian shipping companies between 1885 and 1965. The graphics range from the advertising produced for the first steam ships of the 1880s to those for the ocean liners of the 1920s, cruise liners of the 1930s and, finally, those for the last transatlantic lines in the 1960s. Posters: The Sea Voyage collects placards, posters, announcements, advertising leaflets, brochures and pamphlets produced to promote passenger ships, cruises, sea journeys and Atlantic crossings. In addition to identifying these graphics, text by architect and scholar Pablo Piccione contextualises and historicises the development of Italian graphic styles and tastes. Text in English and Italian.
