Description of the modifications to the Q3 2019-2020 online assessment procedures (Covid-19) |
Review of first-order theories and the corresponding languages (fields, rings, groups, vector-spaces, Boolean algebras, graphs, equivalence relations). Review on the notions of morphisms (isomorphisms, automorphisms, embeddings). Revew on elementary classes. -Chains of structures and theorem on elementary chains. -types and result on realisation of 1-types in an elementary extension. -notion of partial elementary map and link with the property of having the same type and extension of these maps. -Definition and criterium for quantifier elimination (application of the compacity theorem-how to measure the complexity of a formula). -Criterium for elementary substructure and theorems of Lowenheim-Skolem (down and up). -Notion of kappa-categoricity and Vaught theorem. -Cantor theorem on dense linear orders and the go-and-forth construction. -Spaces of types and descrition of the topology (link with the compacity theorem). -Theorem of Ryll-Nardewski (admitting the proof of the omitting type theorem). Notion of an omitted type, atomic models and theorem on the unicity of countable atomic models up to isomorphisms. -------------- written exam of approximated length 3 hours and an half, of the type written synchroneous production. |
