This book is not yet featured on Listopia. Jul 14, Matt Hunt rated it really liked it Shelves: It’s a good book, but ta not quite as amazing as his graph theory book. Nov 21, Alejandro Teruel rated it it was amazing Shelves: A charming and very readable introduction to number theory perfectly pitched for readers with intermediate high school knowledge of mathematics a basic knowledge of divisibility and of Pythagoras theorem is probably sufficient to carry the reader through.
The editors state that: The text niftily and succintly weaves some interesting history, beguiling mathematical problems and, in general, clear proofs of key theorems and assertions together with a smattering of problems to induce the reader to work out and understand the a well chosen set invotation related mathematical concepts.
The books is an entertaining stroll which leads up to the solutions of the Pythagorean equation for which integer values of the three sides are there right-angled triangles? However, this does not detract from the merits of this delightful gem of a book. Nor must he expect to understand all parts of the book on first reading.
He should feel free to skip complicated parts and return to them later; often an argument will be clarified by a subsequent remark”. Finally they are perfectly right in stating that “The best way to learn mathematics is to do invitationn and to that extent the problems set by the author are satisfactory.

Oystein Ore 7 October — 13 August was a Norwegian mathematician. Ore graduated from the University of Oslo inwith a Cand.
Inthe University of Oslo awarded ot the Ph. Inhe was appointed research assistant at the University of Oslo. InYale hired Ore as an assistant professor of mathematics, promoted him to associate professor inthen to full professor in Inhe became a Sterling Professor Yale’s highest academic ranka position he held until he retired in He was a ojstein of the Econometric Society.
Ore visited Norway nearly every summer. In gratitude for the services rendered to his native country during the war, he was decorated in with the Order of St. InOre married Gudrun Lundevall. They had two children. Ore had a passion for painting and sculpture, collected ancient maps, and spoke several languages.
Ore is known for his work in ring theory, Galois connections, and most of all, graph theory.
His early work was on algebraic number fields, how to decompose numbef ideal generated by a prime number into prime ideals. He then worked on noncommutative rings, proving his celebrated theorem on embedding a domain into a division ring. He then examined polynomial rings over skew fields, and attempted to extend his work on factorisation to non-commutative rings. As a teacher, he is notable for teaching mathematics to two doctoral students who would make vital contributions to science and mathematics: Grace Hopper, who would eventually become a United States rear admiral and computer scientist who invitatoin vital to the development of the first computers, and Marshall Hall, Jr.
He then turned his attention to lattice theory becoming, together with Garrett Birkhoff, one of the two founders of American expertise in the subject. Ore’s early work on lattice theory led him to the study of equivalence and closure relations, Galois connections, and finally to graph theory, which occupied him to the end of his life.
Ore had a lively interest in the history of mathematics, and was an unusually able author of books for laypeople, such as his biographies of Cardano and Niels Henrik Abel. Trivia About Invitation to Num No trivia or quizzes yet.
