| Popis: | We classify the connected orientable 2-manifolds whose mapping class groups have a dense conjugacy class. We also show that the mapping class group of a connected orientable 2-manifold has a comeager conjugacy class if and only if the mapping class group is trivial. Comment: v4: Final version, incorporated referee's comments, to appear in Math. Z. v3: There was an error in the previous version's Lemma 6.1: this lemma has been removed and the statement of the main theorem, now Theorem 6.1, has been updated accordingly (see Remark 6.2 for more details). v2: Updated and corrected some wording; v1: 32 pages, 5 figures |
