2022.04.06 MATH 3600 Erdos Strauss

87 days ago by calkin

We are discussing the Erdos Strauss conjecture: if $n \geq 2$

\[  \frac{4}{n} = \frac{1}{a} + \frac{1}{b} + \frac{1}{c} \]

has positive integer solutions $a,b,c $

Write code to find all solutions for 4/n.  See how the number changes.

Examine what happens for primes.  Compare primes and composite n.
