The three particular polygonal are:[br][br]- The logarithmic polygonal spiral with constant angular step.[br]- Regular polygons.[br]- The last divergent polygonal spiral present in the traces resulting from a formulation of the Riemann zeta function.[br][br]I published a preprint on zenodo.org in which I present two methods for the first and third polygonals that allow us to identify the origin of the spirals.[br][br]This is the link for the English version http://doi.org/10.5281/zenodo.10137173[br][br]This is the link for the Italian version http://doi.org/10.5281/zenodo.10137031
