The ABC conjecture [La conjecture ABC].




The horizontal and vertical axes display respectively the integer numbers from 1 to N. Each disk display a couple of coprime numbers A (X axis) and B (Y axis): 
                    GCD(A,B)=1
The number C is the sum of A and B: 
                    C = A+B
The function Radical(N) gives the product of the prime factors (with an exponent equals to 1) of N. For example: 
                    N = 1960 = 23x51x72

                    Radical(1960) = 21x51x71 = 2x5x7 = 70


Then the following function is computed: 
                                      log(C)
                    k(A,B,C) = ---------------------
                                log(Radical(A.B.C))
The ABC conjecture states that k(A,B,C) is less than a certain constant (unknown, but greater than 1 and hopefully lesser than 2...) whatever the values of A and B.



The surface and the luminance of each disk are proportional to k(A,B,C).

For this picture, the numbers A and B belong to [1,N=50] giving birth to the following values: 
                    min(k(A,B,C))=0.37117806024788
                    max(k(A,B,C))=1.22629438553090
