Monochromatic Regular Polygons in finitely colored $\mathbb{Z}_2 *\mathbb{Z}_2 *\mathbb{Z}_2$
arXiv:1807.09411
Abstract
We show that for any finite coloring of the group $\mathbb{Z}_2 *\mathbb{Z}_2 *\mathbb{Z}_2$ and for any positive integer $k$, there always exists a monochromatic regular $k$-gon in $\mathbb{Z}_2 *\mathbb{Z}_2 *\mathbb{Z}_2$ with respect to the word length metric induced by the standard generating set; the edge length of which is estimated.
