报告摘要:A groups presentation is cyclically presented is has n generators and n relations, where all relations are obtained from the initial one by the automorphism which permute generators cyclically. These groups naturally arise in the low-dimensional topology and the theory and in the hyperbolic geometry as fundamental group of three-dimensional manifolds. We will present the relations of these groups with n-valued groups and corresponding branched coverings.
