Quadrature of lunes
Posted:
Jan 5, 2006 1:38 PM


Hi, there!
Due to its importance in the history of mathematics there is extensive literature on Hippocrates lunes. However, except for the original papers of Tschebotarow and Dorodnov I was not able to find in the literature a proof of the existence of exactly five squarable lunes. In particular, I am having problems understanding one of the cases in Tschebotarow's original proof (case 4. on page 174 of the paper N. Tschebotarow: Uber quadrierbare Kreisbogenzweiecke I, Mathematische Zeitschrift 39 (1934), pp. 161175): How to see that the polynomial x^27  1  sqrt{27/11) x^8 (x^11  1) has no factor of degree some power of 2. Tschebotarew suggests using reductions modulo 3 and modulo 11.
Any help would be greatly appreciated.
Best, Tomaz
