On the afternoon of August 9, Hanoi National University Publishing House held a seminar to launch the book "Elementary Number Theory - Elementary Methods in Number Theory" authored by Professor Ngo Bao Chau and Dr. Do Viet Cuong, lecturers at the University of Natural Sciences - Hanoi National University.

This is the first Mathematics book written and published in Vietnam by Professor Ngo Bao Chau, with the participation of Dr. Do Viet Cuong. The book is written in Vietnamese, 16x24, with 588 pages. At the same time, the book also marks the first collaboration between Professor Ngo Bao Chau, the Institute for Advanced Study in Mathematics and Hanoi National University.

With the aim of providing a comprehensive and up-to-date foundation in number theory, the book serves both undergraduate and graduate students in Mathematics and Mathematics Education, as well as excellent students in mathematics at high schools, and those who love mathematics. The authors have used many classic documents and existing textbooks to build the content, and at the same time supplemented with new and deeper knowledge.

Professor Ngo Bao Chau shared: “In any case, this is a laborious task. The starting point was just a lecture for students majoring in Mathematics during the Covid-19 pandemic. At that time, I had a training class for excellent students majoring in Mathematics on number theory in grades 9, 10, and 11.

Normally, I don't prepare those lectures because I have given them many times, but because I teach via Zoom, I have written a thin textbook of about a few dozen pages. From that textbook, with the encouragement of some colleagues, I compiled it into a book. At first, it was very sketchy, but it gradually became more and more solid, especially with the support of Mr. Do Viet Cuong, the book was born."

Professor Chau said that he spent a lot of time writing and presenting, not wanting to “just talk vaguely” about Mathematics. There were even some knowledge that he had to learn more about.

“There are many problems in number theory that I don’t know or know but not clearly, so I have to learn more. I’m not excited to see it come out, but excited to see how it will be received. People have received it very positively, so for me, it’s a great joy,” he said.

The book builds a rich system of exercises and solutions to help learners consolidate knowledge and gain a deeper understanding of number theory. The author hopes that this will be a study and research document that not only helps learners grasp the basic and advanced concepts of number theory, but also inspires passion and motivation for further research in mathematics.

Dr. Tran Quoc Binh, Director of Hanoi National University Publishing House, believes that the book will be a study and research document to help learners grasp basic and advanced concepts of number theory.

"Books also inspire passion and motivation for further research in Mathematics," said Mr. Binh.
