The Barcelona conjecture:

Let c=(x+y+z)^p/(pxyz2^p)

for integer c,x,y,z and p prime greater than or equal to 5, the
Barcelona conjecture is that no solutions exist with gcd(c,xyz)=1 (no
c exist that shares no factor with x or y or z).

While this is a very interesting problem in itself (the heart of it is
the relation between the factors of a sum versus the product of the
addends - ie (x+y+z)^p/(xyz)), and may at first seem to be easy to
resolve, it is in fact intimately related to Fermat's Last Theorem.
In fact, proving the Barcelona conjecture also proves FLT (no integer
ABC that satisfy A^p+B^p=C^p for p prime greater than 2) for prime
exponents greater than 3. [note that letting c=1 for p=3 solves
this exponent for FLT]

There are integer solutions to the above, but all found to date have a
factor in common for c and xyz.

Regards to all.

I haven't seen this conjecture before, but compare the Beal conjecture:

The Beal conjecture is a stronger statement than FLT. Also, it seems to be
less arbitrary-looking and more natural, at least to me. I'll let you know
when I prove it Smile

Yes, I was aware of the Beal conjecture and briefly attempted to prove
it also :)

The reason you hadn't seen the Barcelona conjecture is that it is
virtually unknown outside of this newsgroup since I've only posted it
here and in the research math group. I came up with it while
attempting to prove FLT using elementary techniques ( ok, once we are
done laughing the question remains - who hasn't? I mean even JSH keeps
on trying.)

In some respects it should be easier to prove FLT using the Barcelona
conjecture as the latter places less restrictions on the value of c -
maybe even Fermat was working on this approach as it only requires
elementary methods, though I really doubt it as it isn't documented in
Ribenboim's book on FLT.

If anyone can lend me a hand I'm trying to get a grip on how FLT was
tied to elliptic curves, my goal being to see how feasible it is to
apply the same methods to the Barcelona conjecture - for the moment it
is way too difficult for me.

Can the equation for c be transformed into an elliptic curve?
