ABC-Conjecture (Masser-Oesterlé, 1985):
Let [tex]\beta[/tex] > 1. Then, with finitely many exceptions, we have C < rad[tex](ABC)^{\beta}[/tex].
In a 'nutshell', for positive integers, A, B, and C we have have:
[tex]\prod_{j_1 =1}^{l_1}[/tex][tex]p_{j_1}[/tex] [tex]\prod_{j_2 =1}^{l_2}[/tex] [tex]p_{j_2}[/tex] [tex]\prod_{j_3 =1}^{l_3}[/tex][tex]p_{j_3}[/tex]
= rad(ABC) = [tex](\frac{C}{\gamma})^{1/{\beta}}[/tex] = [tex](\frac{\prod_{j_3 =1}^{l_3}p_{j_3}^{k_{j_3}}}{\gamma})^{1/{\beta}}[/tex]
for some [tex]{\beta} > 1[/tex] such that:
Case 1: [tex]0 < \gamma < 1[/tex] implies an infinite set of triples, (A, B, C);
Case 2: [tex]\gamma > 1[/tex] implies an empty or finite set of triples, (A, B, C);
according to [tex]0 < \gamma < 2 * \prod_{j_3 =1}^{l_3}[/tex][tex]p_{j_3}^{k_{j_3} - 3\beta}[/tex]
such that gcd(A, B) = gcd(A, C) = gcd(B, C) = 1 with A < B < C = A + B.
Notes:
[tex]k_{j_3}[/tex] represent constants (integers [tex]\ge 1[/tex]) while [tex]\beta \ge 1[/tex] is unrestricted (no upper bound) variable.
Case 1: [tex]0 < \gamma < 1[/tex] also implies [tex]k_{j_3} < 3 \beta[/tex] such that [tex]2 * \prod_{j_3 =1}^{l_3}[/tex][tex]p_{j_3}^{k_{j_3} - 3\beta} < 1[/tex].
Case 2: [tex]\gamma > 1[/tex] also implies [tex]k_{j_3} \ge 3 \beta[/tex] which forces a upper bound on [tex]\beta[/tex]
such that [tex]2 * \prod_{j_3 =1}^{l_3}[/tex][tex]p_{j_3}^{k_{j_3} - 3\beta} > 1[/tex].
And when that upper bound on [tex]{\beta}[/tex] for case 2 is exceeded, there is a solution in case 1.
