內(nèi)容摘要：
For two groups H and K, if a group G satisfies (i) G=HK and (ii) H \cap K = {id}, then we call G a complementary product of H and K. A complementary product of a cyclic group and a group H can be considered with skew morphism of H and its extended power functions. In this talk, we consider complementary products of a cyclic group and a dihedral group. For a dihedral group D of order 2m with odd m, we classified complementary products of a cyclic group and D by classifying all skew morphisms of D and their extended power functions. In this talk, we will also consider full classification of complementary products of a cyclic group and a dihedral group. Using relation between complementary products of a cyclic group and a dihedral group and regul ar generalized Cayley maps on cyclic group, we classified regular generalized Cayley maps on cyclic groups. This is joint work with Istvan Kovacs and Kan Hu.
