Generalizations of the Los-Tarski Preservation Theorem
We present new preservation theorems that semantically characterize the ∃∀ and ∀∃ prefix classes of first order logic, for each natural number k. Unlike preservation theorems in the literature that characterize the ∃∗∀∗ and ∀∗∃∗ prefix classes, our theorems relate the count of quantifiers in the leading block of the quantifier prefix to natural quantitative properties of the models. As special ...
متن کاملAn Intuitionistic Version of Cantor's Theorem
An intuitionistic version of Cantor’s theorem, which shows that there is no surjective function from the type of the natural numbers N into the type N → N of the functions from N into N , is proved within MartinLöf’s Intuitionistic Type Theory with the universe of the small types. Mathematics Subject Classification: 03B15, 03B20.
متن کاملAn intuitionistic version of Ramsey Theorem (italian version)
RIASSUNTO. Il teorema di Ramsey [6] per coppie e’ provabile classicamente ma non intuizionisticamente [2]. In questa nota mostriamo che Ramsey si puo’ rienunciare in una forma intuizionisticamente provabile, informativa (o quanto meno priva di negazioni), e classicamente equivalente all’originale. A differenza di precedenti tentativi, non utilizziamo ne’ il noncontroesempio come in [1], [5], ne...
متن کاملThe Sturm-Tarski Theorem
We have formalised the Sturm-Tarski theorem (also referred as the Tarski theorem): Given polynomials p, q ∈ R[x], the Sturm-Tarski theorem computes the sum of the signs of q over the roots of p by calculating some remainder sequences. Note, the better-known Sturm theorem is an instance of the Sturm-Tarski theorem when q = 1. The proof follows the classic book by Basu et al. [1] and Cyril Cohen’...
متن کاملSturm-Tarski Theorem
We have formalized the Sturm-Tarski theorem (also referred as the Tarski theorem): ∑ x∈(a,b),P (x)=0 sign(Q(x)) = Var(SRemS(P, P ′Q; a, b)) where a < b are elements of R ∪ {−∞,∞} that are not roots of P , with P,Q ∈ R[x]. Note, the usual Sturm theorem is an instance of the Sturm-Tarski theorem with Q = 1. The proof is based on [1] and Cyril Cohen’s work in Coq [2]. With the Sturm-Tarki theorem,...
