,Ehrenfeucht-Fra?ssé Games,ht-Fra?ssé games for first-order logic. We prove the EhrenfeuchtFra?ssé theorem, characterizing the expressive power of FO via games, and introduce the notion of types, which will be central throughout the book.作者: 樂(lè)意 時(shí)間: 2025-3-22 02:52
Ordered Structures,e ordered; on numbers we have arithmetic operations, on strings we have concatenation, substring tests, and so on. As query languages routinely use those operations, one may want to study them in the context of FO.作者: 產(chǎn)生 時(shí)間: 2025-3-22 06:41 作者: 價(jià)值在貶值 時(shí)間: 2025-3-22 11:46
Monadic Second-Order Logic and Automata,esses some NP-complete problems, but at the same time cannot express graph connectivity. Then we restrict our attention to strings and trees, and show that, over them, MSO captures regular string and tree languages. We explore the connection with automata to prove further definability and complexity results.作者: 碌碌之人 時(shí)間: 2025-3-22 13:18
Zero-One Laws,lso see that the “almost everywhere” behavior of logics is drastically different from their “everywhere” behavior. For example, while satisfiability in the finite is undecidable, it is decidable if a sentence is true in almost all finite models.作者: 碌碌之人 時(shí)間: 2025-3-22 20:48

Vincenzo Lattanzio,Giovanni Simonetti on the data complexity. We also consider the issue of . for a circuit model, and study it via logical definability. We then move to the combined complexity of FO, and show that it is much higher than the data complexity. Finally, we investigate an important subclass of FO queries — . — which play a central role in database theory.作者: eulogize 時(shí)間: 2025-3-24 16:31 作者: etiquette 時(shí)間: 2025-3-24 20:13 作者: Licentious 時(shí)間: 2025-3-24 23:55

The Dismal Science: Economic Manications of finite model theory in computational complexity. We start by proving the earliest such result, Trakhtenbrot’s theorem, stating that finite satisfiability is not decidable. For the proof of Trakhtenbrot’s theorem, we code Turing machines with no inputs.
