Abstract
Let \( f:{\Sigma_g}\rightarrow{\Sigma_g}\) be a pseudo-periodic map of negative twist. According to Corollary 4.5, the isomorphism class of the minimal quotient \(\pi:{\Sigma_g}\rightarrow {S[f]}\) and, in particular, the numerical homeomorphism type of S[f] are conjugacy invariants of \( [f]\epsilon {\mathcal{M}_g}\). However, the converse is not true: the minimal quotient does not necessarily determine the conjugacy class of [f]. (Nielsen [50, Sect. 15] incorrectly claims that this converse is true (compare Theorem 13.4 of [22] where this same claim is repeated)).
