Unsolved problems in number theory | Conjectures about prime numbers
At the 1912 International Congress of Mathematicians, Edmund Landau listed four basic problems about prime numbers. These problems were characterised in his speech as "unattackable at the present state of mathematics" and are now known as Landau's problems. They are as follows: 1. * Goldbach's conjecture: Can every even integer greater than 2 be written as the sum of two primes? 2. * Twin prime conjecture: Are there infinitely many primes p such that p + 2 is prime? 3. * Legendre's conjecture: Does there always exist at least one prime between consecutive perfect squares? 4. * Are there infinitely many primes p such that p − 1 is a perfect square? In other words: Are there infinitely many primes of the form n2 + 1? As of October 2022, all four problems are unresolved. (Wikipedia).
Yitang Zhang and The Landau-Siegel Zero Problem in Number Theory [2019] (in Chinese)
Abstract: As a special and (probably) much weaker form of the Generalized Riemann Hypothesis, the Landau-Siegel zero problem has its own interest and amazing applications in number theory. In this talk we will introduce its history and applications. In particular, it will be explained why

What is the Riemann Hypothesis?
This video provides a basic introduction to the Riemann Hypothesis based on the the superb book 'Prime Obsession' by John Derbyshire. Along the way I look at convergent and divergent series, Euler's famous solution to the Basel problem, and the Riemann-Zeta function. Analytic continuation
