Meditations on the Farey Fractal
摘要
We define the “coronas”, which are especially spiky paths in the Farey graphFarey graph going from \(\underline{0}=(1,0)\) to \(\underline{\infty }=(0,1)\) . We show that for \(R\ge 2\) , \(\left\{ (x,y)\in \mathbb {N}^{+}\times \mathbb {N}^{+},\right. \) \(\left. \gcd (x,y)=1, \; x+y\le R \right\} \) is a corona.
