Periodic projections of alternating knots
Abstrak
In this paper we give a positive answer to a conjecture stated in by the authors in RACSAM 112(3) (2018), 793-802, by proving that: (1) any oriented prime alternating knot $K$ which is $q$-periodic, with $q\geq3$, has an alternating $q$-periodic projection. (2) if the prime alternating knot has no $q$-periodic alternating projection, the periodicity of $K$ is necessarily $q=2$. As applications we obtain the crossing number of a $q$-periodic alternating knot with $q\geq3$ is a multiple of $q$ and we give an elemantary proof that the knot $12a_{634}$ is not 3-periodic, our proof does not depends on computer as in "Periodic knots and Heegaard Floer correction terms" by Stanilav Jabuka and Swatee Naik (arXiv:1307.5116 [math.GT], to appear in the Journal of the European Mathematical Society).
