Ramsey classes and sparsity for finite models
Apparaît dans la collection : 2018 - T1 - WS1 - Model theory and combinatorics
In the talk we relate two notions in the title particularly in the context of sparse dense dichotomy (nowhere and somewhere dense classes and stability) and Ramsey classes of finite models in the context of the characterisation programme. A joint work with P. Ossona de Mendez (sparsity) and D. Evans and J. Hubička (Ramsey).
