A Structural Reading of the Beal Conjecture: ...

Type: preprint
Abstract: We summarize an exploratory study of the Beal conjecture $A^x+B^y=C^z \Rightarrow \gcd(A,B,C)>1$ for exponents $x,y,z\ge 3$. Guided by the principle that a proof should come from the structure of theequation rather than from its six free variables, we collect(i) elementary reductions that remove the exponents and the common factor,(ii) a ``repair'' mechanism explaining why every known solution has a common prime,(iii) a case analysis showing where factorization is available (equal exponents,a square term, a base equal to $1$) and where it is not (three distinct odd primes),and (iv) a classification of what is closed and what remains open.Results derived in this discussion are elementary and were checked numerically on examples; they are not claimed to be new.
