On the topology of hypocycloids
Abstract
Algebraic geometry has many connections with physics: string theory, enumerative geometry, and mirror symmetry, among others. In particular, within the topological study of algebraic varieties physicists focus on aspects involving symmetry and non-commutativity. In this paper, we study a family of classical algebraic curves, the hypocycloids, which have links to physics via the bifurcation theory. The topology of some of these curves plays an important role in string theory and also appears in Zariski's foundational. We compute the fundamental groups of some of these curves and show that they are in fact Artin groups.
