The abc conjecture
K≧1, ε>0 The abc conjecture is also based on prime numbers. It must be abc triples which are (a,b,c)=a*b*c, a<b, and a+b=c. You can ignore numbers multiplied by the same. For example, when there are a=1, b=80, c=81, you see 80=2^4*5, and 81=3^4. The radical of (1,80,81) is 1*80*81=1*2*5*3=30 It must be less than c. rad(1,80,81)=30<81. This is the rule of abc triples. It is said that you can find abc triples infinitely. When you see a=1, b=9^n -1, c=9^n, you can't break the rule. 1+9^n -1=9^n. 1<9^n -1 Therefore, (1, 9^n -1, 9^n) is abc triples, if it is less than 9^n. n=1, rad(1,8,9)=6 n=2, rad(1,80.81)=30 n=3, rad(1,728,729)=546 ・ ・ ・ n would be infinite. Then you can see quality of the triple. rad(a,b,c)^q=c q=log(c)/log(rad) It is said that quality of abc triple is greater than 1. q>1 The quality of abc triples is not stable. It keeps waving, but each dot is finite. This is the abc conjecture. You can see the same pattern from p...
