Exterior Power Problem
I need some help with a problem from Dummit and Foote, Chapter 11.5#8c: "8c) Give an example of an integral domain R and an R-module I in F [F = the field of fractions of R] with Lambda^i(I) /= 0 for each i>=0. [i.e. the ith exterior power of I as an R-module is nonzero for each i>=0] (c.f. example following Corolla... 15 Dec 2009 17:50

The Fermat primes are factors of the denominators of the Bernoulli numbers 2^(n+1)
Gerry <gerrymrt(a)gmail.com> writes: Hi All, something i didn't find a reference for and might be of interest. Since the denominators of the Bernoulli numbers are based on the primes 2 * f + 1 for every divisor f of 2^n one can write the following equation which holds for the Fermat primes : ... 14 Dec 2009 14:22

YOUR PARIS BURNING -- RIEMANNS HALF LINE A MATHEMATICAL ABBERRATION
This remains to be verified by your Mathematician in a spirit of understanding and NOT in a spirit of "balls and rectums" that many of you have exemplified to us on sci math . "Balls and Rectums" will not solve your predicament of Riemanns and the mess of Quantum mathematics----- , but Hope research has been able ... 6 Jan 2010 09:21

correlation co-efficient of a joint pdf
Let X and Y have the joint pdf f(x,y)=x+y 0<=x<=1, 0<=y<=1 =0 Elsewhere How do I find the correlation co-efficent between X and Y? Actually, I think my main problem is calculating the Var(X) and Var(Y). I keep getting these very messy expressions that simply can't be right. How do ... 14 Dec 2009 18:51
