What Are Some Recommended Books for Learning p-adic Numbers?

In summary, "p-adic Numbers: An Introduction" by Fernando Gouvea is the most recommended book for learning p-adic numbers. The pre-requisites for reading this book include a basic knowledge of algebra, number theory, and calculus or analysis. The reader should also know about congruences, fields, rings, point-set topology, continuity, and infinite series. These topics are typically covered in undergraduate courses.

Dear Physics Forum friends,

what are some good books for learning the p-adic numbers? What are the necessary pre-requisites?
Do I need to know introductory number theory or basics of algebraic/analytic number theory?

I don't have experience per-se, but I have been thinking of learning the same things, and did a tiny bit of research on books for this a couple months ago.

The most recommended book was "p-adic Numbers: An Introduction" by Fernando Gouvea. In the introduction, Gouvea states that "the pre-requisites for reading this book are a basic knowledge of algebra and number theory, and a few courses in calculus or analysis." He says the reader needs to know congruences, fields and rings, and the basic facts of point-set topology, continuity, and infinite series. From context, he probably means you need to know the basic topology and properties of continuity and infinite series one learns in an undergraduate analysis course.

FAQ: What Are Some Recommended Books for Learning p-adic Numbers?

What are p-adic numbers?

P-adic numbers are a type of number in mathematics that were first introduced by German mathematician Kurt Hensel in the early 20th century. They are an extension of the rational numbers and are important in number theory and algebraic geometry.

Why are p-adic numbers important?

P-adic numbers have many applications in mathematics, including in number theory, algebraic geometry, and representation theory. They also have practical applications in cryptography and coding theory. P-adic numbers also have connections to other areas of mathematics, such as topology and complex analysis.

What is the difference between p-adic numbers and real numbers?

The main difference between p-adic numbers and real numbers is the way they are constructed. Real numbers are based on the decimal representation of numbers, while p-adic numbers are based on the p-adic representation, which uses a different base. Additionally, p-adic numbers have different properties than real numbers, such as the fact that they are not totally ordered.

How are p-adic numbers used in cryptography?

P-adic numbers are used in cryptography because they have different properties than real numbers, making them useful for creating secure codes and encryption methods. P-adic numbers are also used in coding theory, which is important for error correction in data transmission.

Are there any books about p-adic numbers for beginners?

Yes, there are several books about p-adic numbers that are suitable for beginners, including "p-adic Numbers: An Introduction" by Fernando Quadros Gouvea and "A Course in p-adic Analysis" by Alain M. Robert. Additionally, many introductory books on number theory or algebraic geometry also cover p-adic numbers.
