This volume presents the proceedings from the Eleventh
Brazilian Logic Conference on Mathematical Logic held by the Brazilian
Logic Society (co-sponsored by the Centre for Logic, Epistemology and
the History of Science, State University of Campinas, São Paolo) in
Salvador, Bahia, Brazil. The conference and the volume are dedicated
to the memory of professor Mário Tourasse Teixeira, an educator and researcher who
contributed to the formation of several generations of Brazilian
logicians.

Contributions were made from leading Brazilian logicians and their
Latin-American and European colleagues. All papers were selected by a
careful refereeing processs and were revised and updated by their
authors for publication in this volume.

There are three sections: Advances in Logic, Advances in
Theoretical Computer Science, and Advances in Philosophical
Logic. Well-known specialists present original research on several
aspects of model theory, proof theory, algebraic logic, category
theory, connections between logic and computer science, and topics of
philosophical logic of current interest. Topics interweave
proof-theoretical, semantical, foundational, and philosophical aspects
with algorithmic and algebraic views, offering lively high-level
research results.

#### Readership

Graduate students and research mathematicians interested in mathematical logic and foundations; computer scientists.
