Bunyakovsky conjecture

The Bunyakovsky conjecture (or Bouniakowsky conjecture) gives a criterion for a polynomial in one variable with integer coefficients to give infinitely many prime values in the sequence It was stated in 1857 by the Russian mathematician Viktor Bunyakovsky. The following three conditions are necessary for to have the desired prime-producing property: 1. * The leading coefficient is positive, 2. * The polynomial is irreducible over the integers. 3. * The values have no common factor. (In particular, the coefficients of should be relatively prime.) Bunyakovsky's conjecture is that these conditions are sufficient: if satisfies (1)–(3), then is prime for infinitely many positive integers . A seemingly weaker yet equivalent statement to Bunyakovsky's conjecture is that for every integer polynomial that satisfies (1)–(3), is prime for at least one positive integer : but then, since the translated polynomial still satisfies (1)–(3), in view of the weaker statement is prime for at least one positive integer , so that is indeed prime for infinitely many positive integers . Bunyakovsky's conjecture is a special case of Schinzel's hypothesis H, one of the most famous open problems in number theory. (Wikipedia).

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

A (compelling?) reason for the Riemann Hypothesis to be true #SOME2

A visual walkthrough of the Riemann Zeta function and a claim of a good reason for the truth of the Riemann Hypothesis. This is not a formal proof but I believe the line of argument could lead to a formal proof.

Norms are equivalent

In this video, I prove two linear algebra facts with an almost identical proof! First, I show that every linear transformation from a finite dimensional vector space to itself must be bounded. Then I show that any two norms on a finite dimensional vector space are equivalent! YouTube chan

A Taste of Calculus of Variations

Dirichlet's Principle In this video, I give you a taste of calculus of variations by illustrating Dirichlet's principle, which says that a function u is a minimizer of a certain Dirichlet energy (kinetic + potential energy) if and only if u solves Poisson's equation. This is a neat way of

Giles Gardam - Kaplansky's conjectures

Kaplansky made various related conjectures about group rings, especially for torsion-free groups. For example, the zero divisors conjecture predicts that if K is a field and G is a torsion-free group, then the group ring K[G] has no zero divisors. I will survey what is known about the conj
