The Goldbach Conjecture: is this statement true? On Jul 7, 2:30 pm, raycb <ra...(a)live.com> wrote: Let p be an odd prime larger than 3. Generate pairs of even numbers 2p + 2 and 2p - 2, 2p + 4 and 2p - 4, 2p + 6 and 2p - 6, and so on, until 2n is reached, where n is the prime that precedes p. Conjecture: each member of a pair can be written as the sum... 7 Jul 2010 14:35

Applying Cauchy formula... Suppose G=G(r,s) is a close, smooth enough path containing the origin. Consider the integral: 1/i2Pi Int_G e^z/z^2 dz My book says this is e^0=1 because this is simply because of Cauchy formula. However it looks like he applies the cauchy formula to e^z/z whose value in zero is definitely not 1. Any hint?... 8 Jul 2010 10:16
Conjecture on integer sequences Conjecture: If a sequence Un is such that LogLog(Un) is of the order Log(n) or less and it contains five or more primes, then the sequence will contains infinitely many primes. (No counting in the five, the numbers used to initiate the algorithm.) This conjecture will comprise many of the unsolved prime conjectur... 9 Jul 2010 10:33
Compactness in metric spaces This question was motivated by a the following problem: Let S be a subset of R^n such that every continuous function from S to R is bounded. Show that S is compact. Since Heine Borel theorem holds in R^n, this is not hard to prove. If S is not compact, then it's unbounded or not closed. If it's unbounded, put f(x) =... 10 Jul 2010 17:07
LADY WINS FOURTH LOTTERY - WHAT ARE THE ODDS? Lady Wins Fourth Lottery: What Are the Odds? By William M. Briggs Wednesday, July 7, 2010 I'm in the wild blue yonder today; so here is a distraction.

Trigonometry help VABC is a regular tetrahedron with base triangle ABC. (All faces are equilateral triangles.) Find the magnitude of the angle between a sloping edge and the base. Let x be the length of any edge. Why doesn't acos{[(x ^ 2 - (x / 2) ^ 2] ^ (1 / 2) / x} yield the right answer? ... 8 Jul 2010 02:39

infinity in the large needs a boundary and infinity in the small needs a boundary #641 Correcting Math Funny how infinity needs a discussion for both large infinity and a separate discussion for infinity on the small scale. Here is another example of Quantum Duality in mathematics in that infinity, which we usually think of as beyond large, that it must be reconciled with microscale and infinity there.

the poper regular model of a elliptic curve Let E be the elliptic curve on \mathbb{Q}_p defined by the equation y^2*z=x(x-z)(x-p*z), then the proper regular model of E is E1 : y^2*z=x(px-z)(x-z) ? I know it is not, but why? I mean, E1 is proper, and regular. Thanks ! ... 6 Jul 2010 23:20 |
