2 Brilliant Unsolved Problems in Number Theory
A brief introduction to the Riemann hypothesis and the Inverse Galois Problem
Number theory, which is the study of whole numbers and their properties, has always been an intriguing subject, not just for mathematicians, but also for those who are aspirants of mathematical disciplines and enthusiasts. Despite the many advancements made in this field over the last several decades, there are still two (out of several other) problems that still need to be solved. These problems have confounded mathematicians for decades and continue to inspire and challenge even prolific mathematicians.
The first of these problems is the Riemann Hypothesis. This is a conjecture about the distribution of prime numbers and their relationship. The hypothesis states that
all nontrivial zeros of the Riemann zeta function, which encodes the distribution of prime numbers, lie on the critical line of 1/2.
The Riemann Hypothesis was first formulated by the German mathematician Bernhard Riemann in 1859 when he presented a paper in which he studied the distribution of prime numbers and the relationship between them. In this paper, he proposed the Riemann Hypothesis as a conjecture about the location of the nontrivial zeros of the Riemann zeta function.
Since its introduction, the Riemann Hypothesis has been the subject of much investigation, with mathematicians around the world seeking to prove or disprove it. Despite many efforts, proof of the hypothesis remains elusive. In 2000, the Clay Mathematics Institute included the Riemann Hypothesis as one of the seven Millennium Prize Problems, offering a million-dollar reward for its solution.
The second problem is the Inverse Galois Problem. This problem asks for the conditions for the existence of a Galois extension of the field of rational numbers with a specific Galois group. It is one of the central questions in Galois theory and despite many efforts, a general solution remains unknown.
The problem was first posed in the mid-19th century, and it continues to be a central open problem in mathematics today, despite many efforts from mathematicians to solve it. It is a fundamental question in the field of Galois theory, which deals with the relationship between algebraic equations and their solutions. It asks about the conditions necessary for a Galois extension of the rational numbers field with a specific Galois group to exist. Over the years, significant progress has been made, and the Inverse Galois Problem has had a significant impact on mathematics and science by inspiring new areas of research and providing a framework for further study.
These problems are not just of academic interest; they have important implications in fields such as cryptography, where the distribution of primes plays a critical role in the security of communication systems. The fact that these problems remain unsolved, despite the best efforts of mathematicians, is a testament to their difficulty and the richness of the field of number theory.
