The study of information-based actions and processes has been a vibrant - terface between logic and computer science for several decades now. Indeed, several natural perspectives come together here. On the one hand, logical s- tems may be used to describe the dynamics of arbitrary computational p- cesses - as in the many sophisticated process logics available today. But also, key logical notions such as model checking or proof search are themselves informational processes involving agents with goals. The interplay between these descriptive and dynamic aspects shows even in our ordinary...

Eis um livro-texto atualizado de teoria de modelos levando o leitor das primeiras defi nicoes ate o teorema de Morley e as partes elementares da teoria da estabilidade. Alem dos resultados padrao tais como os teoremas da compacidade e da omissao de tipos, o livro tambem descreve varias conexoes com a algebra, incluindo o metodo de eliminacao de quantifi cadores de Skolem-Tarski, modelocompletude, grupos de automorfi smos e omegacategoricidade, ultraprodutos, O-minimalidade e estruturas de posto de Morley finito. O material sobre equivalencias vai-e-vem, interpretacoes e leis zero-um pode...

Edited in collaboration with FoLLI, the Association of Logic, Language and Information this book constitutes the refereed proceedings of the 21st Workshop on Logic, Language, Information and Communication, WoLLIC 2014, held in Valparaiso, Chile, in September 2014. The 15 contributed papers presented together with 6 invited lectures were carefully reviewed and selected from 29 submissions. The focus of the workshop was on the following subjects Inter-Disciplinary Research involving Formal Logic, Computing and Programming Theory, and Natural Language and Reasoning.
