# Goldback revisited

donaggie03 writes "Well, my fellow mathematicians, it's that time again. Agostino Prástaro, from the Univeristy of Rome, claims to have proven Goldbach's Conjecture. The 14 page paper,
THE GOLDBACH’S CONJECTURE PROVED (link to pdf) is pre-published on Arxiv. Prástaro claims to have proven the conjecture through commutative algebra and algebraic topology:
Abstract. We give a direct proof of the Goldbach’s conjecture in number theory, formulated in the Euler’s form. The proof is also constructive, since it gives a criterion to find two prime numbers 1, such that their sum gives a fixed even number 2. (A prime number is an integer that can be divided only for itself other than for 1. In this paper we consider 1 as a prime num-ber.) The proof is obtained by recasting the problem in the framework of the Commutative Algebra and Algebraic Topology.
So is this a valid proof? Are there any glaring errors or has this conjecture finally been proven?"

### Glaring Errors? (1)

#### Jane Q. Public (1010737) | about a year and a half ago | (#41003027)

You mean other than the fact that the definition of "prime number" has been changed to include the number 1?

I don't know that it's a "glaring error", but it's certainly a redefinition of the problem.

# Submission Text Formatting Tips

We support a small subset of HTML, namely these tags:

• b
• i
• p
• br
• a
• ol
• ul
• li
• dl
• dt
• dd
• em
• strong
• tt
• blockquote
• div
• quote
• ecode

### "ecode" can be used for code snippets, for example:

``<ecode>    while(1) { do_something(); } </ecode>``
