Factorization and Primality Testing (Undergraduate Texts in Mathematics) 1989th Edition by David M. Bressoud (PDF)

Description

“About binomial theorems I’m teeming with a lot of news, With many cheerful facts about the square on the hypotenuse. ” – William S. Gilbert (The Pirates of Penzance, Act I) The question of divisibility is arguably the oldest problem in mathematics. Ancient peoples observed the cycles of nature: the day, the lunar month, and the year, and assumed that each divided evenly into the next. Civilizations as separate as the Egyptians of ten thousand years ago and the Central American Mayans adopted a month of thirty days and a year of twelve months. Even when the inaccuracy of a 360-day year became apparent, they preferred to retain it and add five intercalary days. The number 360 retains its psychological appeal today because it is divisible by many small integers. The technical term for such a number reflects this appeal. It is called a “smooth” number. At the other extreme are those integers with no smaller divisors other than 1, integers which might be called the indivisibles. The mystic qualities of numbers such as 7 and 13 derive in no small part from the fact that they are indivisibles. The ancient Greeks realized that every integer could be written uniquely as a product of indivisibles larger than 1, what we appropriately call prime numbers. To know the decomposition of an integer into a product of primes is to have a complete description of all of its divisors.

User’s Reviews

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐Nice introductory text, but the pseudocode is pretty buggy—would definitely recommend checking the author’s errata page before using the given algorithms.

⭐I like the jeans anad the fit. It is hard to find jeans that are “real” denim not the stretchy denim that most are these days. The legs are a little wide but I can live with it espacially in the trouser style.

⭐As far as I can tell this is the first edition of a book written in 1989, almost 20 years ago. Fortunately, the material is still relevant. The author does a good job of presenting the information in a precise manner that is understandable to the reader. Still you will see that the largest Mersenne prime listed in the book is hopelessly out-of-date, and you will find some errors which were never corrected. May I request a second edition for this book as to make it up-to-date?

⭐This is one of the most compact and best organization of material on the subject of factorization and primality.Written by a promising author, this book explores factorization from the beginning to end, starting with the sieve of Eratosthenes and proceeding to much more complicated material. The book focuses on algorithms, and contains many useful ones, such as how to raise a number a to a power b, mod m. However, the primary focus of the book is factorization, so it contains algorithms for factorizations. They begin with trial division, then progress into Fermat’s Algorithm and Pollard Rho. They eventually evolve into one of the strongest methods to date, Quadratic Sieve, and its child, Multiple Polynomial Quadratic Sieve.This book is certainly a must for amateurs who are exploring the subject.

⭐This book explains factorization and theory about primes. It is very good, because it is easy to read. The explanations are well written, and in a lauguage that does not require you to be a master of mathematics. If you want to learn about things like dixons algorithm and the quadratic sieve, then this book is well worth your money. I used the book when writing a report on this subject, and the book was a tremendous help.
