Essays in Constructive Mathematics (eBook, PDF)

• Format: PDF

Produktbeschreibung

This book promotes constructive mathematics not by defining it or formalizing it but by practicing it. This means that its definitions and proofs use finite algorithms, not `algorithms' that require surveying an infinite number of possibilities to determine whether a given condition is met. The topics covered derive from classic works of nineteenth century mathematics - among them Galois' theory of algebraic equations, Gauss's theory of binary quadratic forms and Abel's theorem about integrals of rational differentials on algebraic curves. For Abel's theorem the main algorithm is Newton's polygon, which is given a full treatment. Other topics covered include the fundamental theorem of algebra, the factorization of polynomials over an algebraic number field, and the spectral theorem for symmetric matrices.

Autorenporträt

Harold M. Edwards is Emeritus Professor of Mathematics at New York University. His previous books are Advanced Calculus (1969, 1980, 1993), Riemann's Zeta Function (1974, 2001), Fermat's Last Theorem (1977), Galois Theory (1984), Divisor Theory (1990) and Linear Algebra (1995). Readers of his Advanced Calculus will know that his preference for constructive mathematics is not new. In 1980 he was awarded the Steele Prize for mathematical exposition for the Riemann and Fermat books.

Rezensionen

"A book of this kind with significantly worked-out algorithmic calculations, including many examples, is a rare valuable product." (Wim Ruitenburg, Mathematical Reviews, April, 2024)

"This is the second edition of Harold Edwards' Essays in Constructive Mathematics ... . The essays contained in this volume are serious works of mathematics done from a constructivist perspective. ... I think that most mathematicians already familiar with these topics will find Edwards' constructivist approach to the topics covered to be fascinating." (Benjamin Linowitz, MAA Reviews, December 31, 2023)
