Szpiro’s conjecture is closely related to the ABC conjecture that was proposed by Masser and Oesterlé in 1985. The ABC Conjecture 11.4. (Masser–Oesterlé) For every $\epsilon>0$ there exists a constant $\kappa_\epsilon$ such that for all nonzero integers $A,B,C\in\mathbb Z$ satisfying $A+B=C$ and $\gcd(A,B,C)=1$, we have $\max\{|A|,|B|,|C|\}\leq\kappa_\epsilon\left(\prod_{p\mid ABC}p\right)^{1+\epsilon}$.
