2016br. Nella misura in cui le leggi della matematica si riferiscono alla realtà non sono certe. E nella misura in cui sono certe, non si riferiscono alla "realtà". In tale antinomia A.Einstein descrisse l'incompatibilità tra l'idea di certezza e quella di precisione, ovvero la profonda crisi epistemologica che caratterizzò il pensiero scientifico del novecento: l'indeterminazione concettuale dei fenomeni, l'indicibilità di alcune asserzioni logiche e la vaghezza del rapporto tra mondo reale e mondo linguistico. A far seguito a tale rivoluzione paradigmatica, il tempo dimostrò presto i limiti della logica classica quale strumento inferenziale per descrivere la complessità della realtà. La logica fuzzy, valorizzando i paradossi e le ricorsività proprie della realtà, facilita la modellizzazione di sistemi complessi. L'autorevolezza della logica fuzzy risiede nella capacità di rappresentare la realtà mediante valori diversi dai semplici vero-falso, bianconero o 0-1, insite nella tradizione della logica classica, ma valutando tutte le sfumature di un mondo fatto principalmente di grigi, di verità parziali e di valori continui, anche di quelli apparentemente scollegati tra loro. Nel corso del testo, dopo una divulgativa introduzione ai principi della logica fuzzy, saranno affrontate in forma discorsiva alcune questioni, fortemente differenziate tra di loro, ma con in comune i caratteri propri della complessità del mondo...

NO owner's name or bookplate. Pages are clean and unmarked. Relation theory. Ph.D. thèses présentées a la faculté des sciences de l'université de Paris. soutenues le 29 octobre 1953. Text in French with English summary. This work was reviewed by Paul Dedecker in Alonzo Church's JOURNAL OF SYMBOLIC LOGIC Volume 22 Issue 4 1957 371-372. The French mathematical logician Roland Fraïssé 1920-2008 received his doctoral degree from the University of Paris in 1953. In this his thesis Fraïssé devised a method of determining elementary equivalence. Using a back-and-forth methodology he determined whether two model-theoretic structures were elementarily equivalent. It was later formulated as the Ehrenfeucht-Fraïssé game. This is one of several dozen books and periodicals from Alonzo Church's library that we were lucky enough to purchase at auction in New Jersey. Several of the books contain his signature or a presentation inscription to him. Unfortunately this copy does not have those signs of his ownership. But please check our inventory for several others that do. Alonzo Church 1903 - 1995 was professor of mathematics at Princeton University 1929-1967 and of mathematics and philosophy at UCLA 1967-1990. He was the founding editor of the JOURNAL OF SYMBOLIC LOGIC. Among his most influential contributions are Church's Theorem Church's Thesis the Church-Turing Thesis and the Lambda Calculus. His work was of major importance in mathematical logic recursion theory theoretical computer science and functional programming languages in general. Professor Church's creation of lambda calculus was the foundation for the LISP programming language and provided the semantic model for ALGOL. Church was first to demonstrate that David Hilbert's Entscheidungsproblem was unsolvable. It was Church who coined the phrase "Turing machine" for Alan Turing's hypothetical universal computing machine. He was elected to the National Academy of Sciences British Academy and the American Academy of Arts and Sciences. Church is regarded by many as the greatest American logician of the 20th century.
