Abstract

In this paper, we established the group Γˆ 0,n (N) by group Γ 0,n (N) extending with reflection. Then, we obtain boundary components in signature of the group and we get some calculation for link periods 2, 3, ∞. And then, we constitute chain of reflections with fixed points via Extended Hoore-Uzzell Theorem in the group. Finally, The number of boundary components in the signature of some groups Γˆ 0,p (p) and Γˆ 0,p (p2), p is a prime number, and the number of link periods was found.


Keywords

Signature, Boundary component, Extended Modular Group, NEC Group, Hoare-Uzzel Theorem.
