Lecture 1
From Assignments to Teams
History and precursors, an introduction to team semantics across propositional, first-order, and modal settings, plus closure properties, dependencies, axioms, and information states.
ESSLLI 2026 Course
This course introduces team semantics, a family of logical frameworks in which formulas are evaluated with respect to sets of assignments rather than single assignments. The course approaches the topic through its linguistic and philosophical applications.
Along the way, we will study how team-based methods illuminate free choice and disjunction, questions, indefinites, and dependence, while also connecting the framework to broader topics such as truth, modality, negation, and compositionality.
The course combines formal development with conceptual discussion and is designed to give participants a solid foundation for engaging with current research at the intersection of logic, language, and philosophy.
The course is aimed at graduate students and advanced undergraduates in linguistics, philosophy, logic, and related fields. It should also appeal to researchers in adjacent areas, especially theoretical computer science.
Familiarity with first-order logic is recommended. Prior coursework or independent interest in formal semantics, philosophical logic, or mathematical logic is helpful.
