ESSLLI Summer School course
Prague, Czech Republic, August 3-7 (the first week), 2026
Lecturer: Fan Yang (Utrecht University, The Netherlands)
This course provides a concise introduction to logics of dependence and independence (DIL), which are formalisms for reasoning about dependence and independence relations in sciences. We will study the novel semantics of DIL--team semantics. The basic idea of team semantics is that dependency properties can only manifest themselves in multitudes, and thus formulas of DIL are evaluated on sets of assignments (called teams) instead of single assignments as in the usual Tarskian semantics. A team can be naturally viewed as a database, a dataset, an information state, etc. Thanks to the simple structure of teams and the abundance of their interpretations in various fields of science, DIL have found a number of applications in addressing issues in database theory, social choice, quantum theory, formal linguistics, and so on.
This introductory course covers the fundamentals of team semantics and the core theory of first-order and propositional DIL.
