Brennan conjecture

The Brennan conjecture is a mathematical hypothesis (in complex analysis) for estimating (under specified conditions) the integral powers of the moduli of the derivatives of conformal maps into the open unit disk. The conjecture was formulated by James E. Brennan in 1978. Let W be a simply connected open subset of with at least two boundary points in the extended complex plane. Let be a conformal map of W onto the open unit disk. The Brennan conjecture states that whenever . Brennan proved the result when for some constant . Bertilsson proved in 1999 that the result holds when , but the full result remains open. (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

Proof: A'-B' = B-A (Double Inclusion) | Set Theory

We prove A'-B'=B-A. That is, the complement of A minus the complement of B equals B minus A. We prove this using double inclusion, meaning we prove both sets are subsets of each other, which by definition establishes set equality. This will require basic applications of set theory definiti

How to Prove Math Theorems | 1st Ex: Even + Odd = Odd

Our first math proof! The main goal of this video is more about the structure of a direct proof than the specific claim, that the sum of an even integer and an odd integer is an odd integer. We will write: 1) The Assumptions 2) Definition of the Assumptions 3) Manipulations 4) Definition

Proof of Ramsey's theorem

Ramsey theory is based on Ramsey's theorem, because without it, there would be no Ramsey numbers, since they are not well-defined. This is part 2 of the trilogy of the Ramsey numbers. Useful link: https://en.wikipedia.org/wiki/Ramsey%27s_theorem#2-colour_case Other than commenting on the

What is the Symmetric Difference of 2 Sets?

What is the symmetric difference of 2 sets? In this video we go over the symmetric difference of sets, explaining it in a couple ways including what is probably the briefest way. The symmetric difference of two sets A and B is (A union B)-(A intersect B). If you need to know what the defin

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.
