  • 6:15 The reason π is used for pi, is because the word circumference in greek is περίμετρος which has the first letter π. The reason π(x) is used is because the prime numbers in greek are called πρώτοι αριθμοί which litterally translates to first numbers. Yet again π is the first letter. Coincidental that the letter is the same.

It has a simple formula for Re(z) > 1, but to understand how it's defined elsewhere you need to understand analytic continuation. From my understanding there is only one function on the complex plane that is analytic everywhere except at 1 and matches the formula where Re(z) > 1. And if the OP is reading this, "analytic" on the complex numbers means it's differentiable everywhere it's defined.

  • 11:38 Brady touches upon a very important (but seemingly innocuous) question about pure science and applied science. Engineering is also applied science in action. Any engineer will tell you the amount of assumptions, scenarios etc. that we 'limit' a case to just so that we get closer to the answer for that specific instance. Just a short example, we know that the earth is spherical, but all spheres are locally plane (flat) and that is why we make do with flat rulers to measure the length of a table for instance. Because for most ordinary measurements it is enough to assume that we are dealing with flat surfaces. So even though 99.9% leaves out a lot of numbers, but for a specific case 99.9% is as close to a perfect result one might get.

All that to say, it was a great Q, but you should have kept pushing for an answer! :P

    • "Leveling out" is meant in the limit as x goes to infinity - do the number of primes with each allowed digit converge to the expected mean value? The point is that you allow b to grow as well, not just x. To illustrate an extreme example, suppose you consider all the primes up to b/2 in base b (eg all the primes up to 500 in base 1000). No matter what b you pick, the result is very far from being uniform across all the allowed digits: the larger half of your digits are never reached at all! Taking b to infinity doesn't help: no matter what b you pick, half of your digits will get nothing. A more interesting example is considering all the primes up to b in base b. There still just aren't enough primes to go around; even if you take b to infinity, you'll always find many "allowed" digits with zero primes having that digit (never getting anywhere close to the expected average) But if you consider way more primes, say all primes up to 10^b in base b, and you take b to infinity, then the proportion of primes with each last digit DOES converge to the expected mean. The digits themselves are changing because you're changing the base b; I'm saying that as you increase b, no matter what base-b digit you pick, the ratio between the expected average number of primes with that digit and the actual number gets closer to 1 the larger b gets. The Riemann hypothesis would say that you don't need nearly that many primes in order to see the convergence: just taking all the primes up to b^2 in base b would be enough. The 2023 result says the same thing happens if you only consider all primes up to b^1.63 - though this only holds for "most" b. That is, as you increase b, it's possible that for some very sparse sequence of bases, the distribution jumps away from being uniform; but as long as you take a sequence of bases b that avoids these rare troublemakers, then the proportion of primes up to b^1.63 with each allowed last digit converges to the expected value as b goes to infinity.

But, from what I understand, Fermat's Last Theorem has now been proven. It's sort of a "race" between finding a single counterexample to the Riemann Hypothesis and finding a proof for it. I'm rooting for the proof, of course, but a counterexample would be fascinating.

    • The connection with the Riemann hypothesis is that it yields better approximations of the prime counting function. The generalized Riemann hypothesis then gives better approximations for Dirichlet L functiona which is what you want for this problem in particular. If you do some contour integration and use Perron's forumula, you can show that the Riemann hypothesis is equivalent to the bound psi(x) = x + O(sqrt(x)log(x)) which with some more integration can be shown is equivalent to the bound pi(x) = Li(x) + O(sqrt(x)log^2(x)). You get something similar for the Dirichlet L functions under the GRH which is what is really being used here.

    • The Riemann Hypotheses only gets you to 1/2 for this particular question. But if proven, it always works. There are other ways to get similar results, and actually stronger results (ie you get to evenness faster) but only work most of the time. These other ways have been proven.

    • @@billcook4768From my understanding the results are not necessarily stronger than the Riemann hypothesis but rather allow to you to do away with it and achieve the required result. Case in point here we see that RH asserts the statement is true for all b < sqrt(x) but then Bombieri-Vinogradov a slightly weaker result show that the statement holds for almost all b's which isn't equal to RH which says that it holds for all b, but this result allows us to do away with RH in some of the cases. Even the subsequent statements are just but the tightening of Bombieri-Vinogradov theorem

  • He never defined "evens out", he just said it's about the standard deviation. Be a bit more formal next time maybe? Also he's waving hands a lot and not explaining how the Riemann Hypothesis based result works, or any other results. Also not being able to give examples of bases that work for b < x^0.617 makes it even more vague. Maybe we proved that it works for all b < x^0.617, pushing the upper bound for b a bit beyond what we could prove using RH? I'm left with a bit of confusion on what exactly is the result that I should be excited about.

There's this handwaving feel about how meticulous you are in the distribution being equal, versus the tiny incremental testing of x.617. It sounds like digging to be exact while handwaving the parts that say you're exact.

For example, it could fail for the primes, or for the powers of 2, or for the set {1, 50000000}, or never. The point is that we know it works “every” time.

    • That's because the thing that makes primes special is that every single one of them introduces a new rule that only it breaks. No prime is divisible by 2, except 2. No prime is divisible by 5, except 5. No prime is divisible by 23, except 23. And so on for every prime. It just happens that 2 and 5 are the ones that are visible in the last digit because they're the factors of 10 which we chose as our base to write numbers in.

    @DavidPanofsky@DavidPanofsky6 ай бұрын
    • So part of the reason this is tricky to answer is that the relationship is not actually to non-trivial zeros of the zeta function, but to non-trivial zeros of a more general class of functions known as L-functions (this is the "generalized" part of the "Generalized Riemann Hypothesis"). Now, the x^1/2 bound seen here is directly tied to the conjecture that non-trivial zeros of l-functions lie on the critical line Re(z) = 1/2, just as in the Riemann Hypothesis. Very loosely speaking (I don't understand the details myself), the Bombieri-Vinogradov theorem can be viewed as saying something about how the zeros of different L-functions interact, rather than saying something stronger about just one L-function. That's why it's a bit "orthogonal" to the GRH: it is in one way stronger by saying things about multiple functions at once, but weaker in terms of what it's claiming about those functions - namely, just some amount of cancellation between their zeros, rather than restraining them all to a line.
