Herzog-Schonheim conjecture, vanishing sums of roots of unity and convex polygons
Let be a group and ,\ldots, be subgroups of of indices
respectively. In 1974, M. Herzog and J. Sch\"onheim
conjectured that if , , is a coset
partition of , then cannot be distinct. In this paper, we
present the conjecture as a problem on vanishing sum of roots of unity and
convex polygons and prove some results using this approach.Comment: arXiv admin note: substantial text overlap with arXiv:2001.03882,
