About The Book

Let us refresh our memories by remembering the well-known quotes of Gauss and Laplace, two of the greatest mathematicians of 18th-19th centuries, and take a vow to preserve the beauty of Arithmetic, the Queen of Mathematics, in terms of simplicity associated with the Indian ingenuity in expressing all the numbers by means of ten symbols only.

Mathematics, particularly the arithmetic of natural numbers, is not that though as it has been made out. This dictum of the author, having more than 45 years of teaching and research experience, holds good for research level problems also. But to experience this one has to go through this book entitled "FLT and some other outstanding number theory problems with their arithmetical solutions" wherein Goldbach conjecture and 3x+1 conjecture have also been proved by going into their genesis, while keeping intact their frame of reference. The solutions to most of such problems have to be simple but if they are getting tougher and complicated then there must be some problem with the approach adopted to solve it.
Though this book deals with research level problems but the approach adopted to solve them can also be easily understood by students and teachers at undergraduate level. In fact, it provides new path-breaking and thought-provoking research methodologies by which many more unsolved problems in number theory can be approached to arrive at their long-pending solutions.

About The Author

Vishnu K. Gurtu -

A product of internationally known University of Allahabad, Prof. (Dr) Vishnu Kumar Gurtu, joined Nagpur University’s prestigious Laxminarayan Institiute of Technology in 1967 and retired from active service in 2000. Initially he worked on astrophysical problems but from 1989 onwards he got involved is some challenging number theory problems like Fermat’s Last Theorem (FLT), separating prime and composite numbers from positive integers, Goldbach conjecture etc.

He is a multifaceted personality having interest, up to creative level, in diverse fields such as academic administration, music, literature, philosophy and human psychology. He loves taking up challenges in life and believes that the real solution of any problem, mathematical or otherwise, can be found only by going into its genesis. At age 67, he is continuing his research activities in different fields of his interests. In August 2006, he presented two proofs of FLT at the international Congress of Mathematicians held at Madrid, Spain; one proof which uses techniques available during 17th century goes to justify Fermat’s claim of having a marvelous demonstration of his proposition (FLT).
