We construct some hyperbolic hyperelliptic space forms wh-ose fundamental groups are generated by only two or three isometries. Each occurring group is obtained from a supergroup, which is an extendedCoxeter group generated by plane reections and half-turns. Then wedescribe covering properties and determine the isometry groups of theconstructed manifolds. Furthermore, we give an explicit construction ofspace form of the second smallest volume nonorientable hyperbolic 3{manifold with one cusp.
Abstract
We construct some hyperbolic hyperelliptic space forms wh-ose fundamental groups are generated by only two or three isometries. Each occurring group is obtained from a supergroup, which is an extendedCoxeter group generated by plane reections and half-turns. Then wedescribe covering properties and determine the isometry groups of theconstructed manifolds. Furthermore, we give an explicit construction ofspace form of the second smallest volume nonorientable hyperbolic 3{manifold with one cusp.
