What is distance? (Popular Lectures in Mathematics) – Shreider

In this post, we will see the book What Is Distance? by Yu. A. Shreider. This is part of Popular Lectures in Mathematics series.

About the book

This introduction to the theory of metric spaces carries the student through the motivation, development, and application of an abstract mathematical concept. Yu. A. Shreider begins with a definition of mathematical concepts and then, to motivate his definition of “ metric space,” the author evaluates distance functions and their properties in elementary geometry. After introducing two sets of metric space axioms, he surveys the properties of open balls, sequences, Cauchy sequences, complete metric spaces, and isometries. In the following chapter, the author offers a number of informative examples.

Professor Shreider turns next to applications of the theories, especially the theory of coding and cybernetics. Then returning to theory, the author defines an n-dimensional vector space over real numbers and develops the theory of norms and metrics
on Euclidean n-space. The final chapter considers the possibility of generalizing the concept of metric space.

The book was adapted from the Russian edition by Leslie Cohn and Harvey Edelberg
and was published in 1974.

The Method Of Trigonometric Sums In The Theory Of Numbers – Vinogradov

In this post, we will see the book The Method Of Trigonometric Sums In The Theory Of Numbers by I. M. Vinogradov.

About the book

Since 1934 the analytic theory of numbers has been largely transformed by the work of Vinogradov. This work, which has led to remarkable new results, is characterized by its supreme ingenuity and great power.

Vinogradov has expounded his method and its applications in a series of papers and in two monographs, which appeared in 1937 and 1947. The present book is a translation of the second of these monographs, which incorporated the improvements effected by the author during the intervening ten years.

The text has been carefully revised and to some extent rewritten. The more difficult arguments have been set out in greater detail.

Notes have been added, in which we mention the more im­portant changes made and comment on the subject-matter; we hope these will be of assistance or of interest to the reader.

The book was translated from Russian by K. F. Roth and Anne Davenport and was published in 1954.
