 Apr14 awarded Popular Question Jul2 awarded Curious Apr5 comment Missing one link in logic of basic unique factorization argument Wait, that's not right. Only that when in lowest terms the equality holds. And then each side can be multiplied (denominator and numerator) by whatever one likes. And the equality still holds since that is the same as multiplying by 1. Phew. I think that settles it. Apr5 accepted Missing one link in logic of basic unique factorization argument Apr5 comment Missing one link in logic of basic unique factorization argument Okay, if we say that the GCD of the GCD of both denominators and the GCD of both numerators is not 1, I think that settles it. So something can be cancelled from one side, or both sides. So P has a multiple in common with R, and A has a multiple in common with K and these two common multiples have a common multiple, that is not 1, then at least one side is not in lowest terms. Is that right? That sounds more right. I thought it still felt funny. Thanks for pursuing and pointing that out. Apr5 comment Missing one link in logic of basic unique factorization argument I suppose there would be not factor common between numerator and denominator. So if there is then it can't be in lowest terms. Okay, thanks for repairing my logical chain, I think I'm convinced. :) Apr5 comment Missing one link in logic of basic unique factorization argument Oh, since P must be a multiple of R and A must be a multiple of K, because of the equality? Apr5 asked Missing one link in logic of basic unique factorization argument Mar25 comment Deligne and the four Weil statements about polynomials over finite fields? @GregMartin that's a good distinction I never thought of making clear before. Mar24 comment Deligne and the four Weil statements about polynomials over finite fields? @Martin Okay, thanks. That pdf looks to be pitched at the right level. At a cursory first inspection. Thanks again.

Obtain values, in some finite field, of the variables of that polynomial, whose coefficients in same finite field, such that the polynomial evaluates to zero. 1 set of such variables is a 'solve' or a solution. The find the number of these is to count the solutions. I believe that Deligne's work had something to do with counting the number of solves.

Mar22 comment A weird question on measuring the randomness of a sequence of integers via expected behavior of gcd Okay so we have a possible measure for randomness by sampling the GCDs and seeing if the occurrence of co-primality reproduces the distribution $1/\zeta(i)$, for i samples. This is good. Geometric progression will always have a GCD with probability 1. Arithmetic I am unsure of. Prime gaps will have pairwise GCD = 2 with probability 1 in the limit, and then GCD = 4, 6, ... with some discoverable distribution. The compressed bytes will likely obey the above 'random' metric, and the text of Naruda is a case that would have to be closely examined in the ring mod 257. Mar22 asked Weierstrass factorization of sine, and related questions Mar22 comment A weird question on measuring the randomness of a sequence of integers via expected behavior of gcd Nice result. The probability that any two selected integers will have a factor n? for sum(1/n*1/n) for all n? sum of reciprocal of squares right.

Good point. Okay, I was hoping that sentence would avoid having to explain what random is. You found me out. Mar15 accepted Simple resource for Lagrangian constrained optimization?
