Equivalence and strong equivalence of actions on handlebodies
John Kalliongis, Andy Miller · Transactions of the American Mathematical Society · 1988
An algebraic characterization is given for the equivalence and strong equivalence classes of finite group actions on 3 3 -dimensional handlebodies. As one application it is shown that each handlebody whose genus is bigger than one admits only finitely many finite group actions up to equivalence. In another direction, the algebraic characterization is used as a basis for deriving an explicit combinatorial description of the equivalence and strong equivalence classes of the cyclic group actions of prime order on handlebodies with genus larger than one. This combinatorial description is used to give a complete closed-formula enumeration of the prime order cyclic group actions on such handlebodies.
