RE: Mersenne: Perfect numbers
A number N is perfect if an only if sigma(N)=2N, where the sigma function is the sum of alldivisors of N, including 1 and N. The sigma function verify: i) sigma(p)=p+1, if p is prime ii) sigma(p^n)=1+p+p^2+...+p^n=(p^(n+1)-p)/(p-1), if p is prime iii) sigma(a·b)=sigma(a)·sigma(b), if gcd(a,b)=1 (it's a multiplicative function) Then, if N=2^(p-1)(2^p-1), with 2^p-1 prime 8a Mersenne prime), we have sigma(N)=sigma(2^(p-1)(2^p-1))=sigma(2^(p-1))sigma(2^p-1)=((2^p-1)/(2-1))(2^ p-1+1)= (2^p-1)2^p=2(2^(p-1))(2^p-1))=2N. There is a partial converse: If N is perfect AND EVEN, then N=2^(p-1)(2^p-1), with 2^p-1 prime. It is not proved the inexistence of perfect odd numbers, althought the minimum cote is very high.
