B. Campos et al., BIFURCATIONS OF LINKS OF PERIODIC-ORBITS IN NONSINGULAR SYSTEMS WITH 2 ROTATIONAL SYMMETRIES ON S-3, Journal of knot theory and its ramifications, 6(2), 1997, pp. 163-176
A topological characterization of all possible links composed of the p
eriodic orbits of a Non Singular Morse-Smale flow on S-3 has been made
by M. Wada. The presence of symmetry forces the appearance of given t
ypes of links. In this paper we introduce a geometrical tool to repres
ent these type of Links when a symmetry around two axes is considered
on NMS systems: mosaics. On the other hand, we use mosaics to study wh
at kind of bifurcation can occur in this type of system maintaining th
e symmetry.
