Refresh didn't work - I keep getting this:

Text Box: In Number Theory, Logic, and Cryptography

Text Box: This page provides a means for authors to have their proposed solutions published. Details will include the name and email address of the author, and the date and time of first submission. #01: Submitted by Jeffrey Cook, 23.00 GMT, Wednesday 23rd May 2007. A proposed proof of the Riemann Hypothesis. I introduce a function useful for defining any random or seemingly random values whether involving figures divided by zero, undefined and infinite limits of both real and imaginary numbers. With this function and a number of related, provable theorems, it is shown that the Riemann Hypothesis is true and brings into play the notion put forth by Jordan that a simple closed curve contains two discontinuous regions—an inside and an outside...

The aim of the proof is first to demonstrate that selecting N random numbers, as shown by Reuben and Hersh, that there is an equal chance of selecting a number with an odd or even number of factors. Then the aim is to show that this also applies from 1 to N... Click here for full text. #04: Submitted by Tony Gaffney, 1.00 GMT, Thursday 5th July 2007. A proposed solution to the Dorabella Cipher.

"It has been known since the time of Euler that an odd perfect number N (if it exists) must have the form N = paQ2...

"Consider a composite natural number n greater or equal to 4. We aim at proving that there is at least one natural number r such as (n-r) and (n+r) are both primes. For obvious reasons r<n-2. Such a number r will be called a "primality radius" of n..." Click here for full text. #07: Submitted by Vernon H Graves 10.30 GMT, Friday 9th January 2009. A proposed disproof of the existence of an Euler Brick. IMPORTANT NOTE: the author acknowledges a significant error in the main proof. However, the solution as provided is still presented here in the hope that the lines of reasoning may inspire others.
