Explore advanced mathematical logic through this comprehensive conference series examining the intersection of model theory with combinatorics and valued fields. Delve into the relationship between formal logical languages and mathematical structures, analyzing how model theory provides powerful tools for understanding "tame" mathematical structures through their definable sets. Investigate three interconnected themes: model theory's applications to additive combinatorics, Szemerédi regularity lemmas, pseudofinite structures, and NIP theories; the model theory of Henselian valued fields with valuation topology, including motivic integration and Berkovich spaces; and applications in geometry, analysis, and number theory through fields with operators and the Pila-Wilkie counting theorem. Examine cutting-edge research on first-order rigidity of arithmetic groups, model-theoretic distality, hypergraph Ramsey theory, automorphism groups of sparse graphs, stable arithmetic regularity lemmas, and quantitative bounds on semi-algebraic sets. Study advanced topics in valued field theory including C-minimal valued fields, tropical motivic integration, perfectoid spaces, globally valued fields, and definable groups in geometric fields. Learn about recent developments in o-minimal structures, Ax-Schanuel theorems for Shimura varieties, non-archimedean geometry, and p-adic integration techniques, while exploring connections between model theory and diverse mathematical areas from differential equations to algebraic geometry.
