Hardcover. Condition: Very Good. First Edition. Pages edges browning. Lightly read. Previous owner name on front free page. Previous owner was Raphael Mitchel Robinson (1911-1995) was an American mathematician. Robinson became a full professor at UC Berkeley in 1949 and retired in 1973. Robinson worked on mathematical logic, set theory, geometry, number theory, and combinatorics. Robinson (1937) set out a simpler and more conventional version of John Von Neumann's 1923 axiomatic set theory. Soon after Alfred Tarski joined Berkeley's mathematics department in 1942, Robinson began to do major work on the foundations of mathematics, building on Tarski's concept of "essential undecidability," by proving a number of mathematical theories undecidable. Robinson (1950) proved that an essentially undecidable theory need not have an infinite number of axioms by coming up with a counterexample: Robinson arithmetic Q. Q is finitely axiomatizable because it lacks Peano arithmetic's axiom schema of induction; nevertheless Q, like Peano arithmetic.…

Paperback. Condition: New. Print on Demand. This book introduces a novel and comprehensive theory of irrational numbers. Putting forth the proposition that all numbers, rational and irrational alike, can be represented as cuts in the rational number system, the author provides an alternative approach to understanding the foundations of mathematics. Through this lens, the book explores concepts such as the ordering of numbers, the fundamental operations of arithmetic, and the relationship between rational and irrational numbers. Building upon the work of Dedekind, the author's innovative approach sheds new light on the nature of numbers and the foundations of mathematics, offering a valuable resource for mathematicians, students, and anyone interested in the history and philosophy of mathematics. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
