Disconnectedness of the subgraph F-3 for the group Gamma(3)
(Springeropen, 2013)
In this paper we show that the subgraph F-3 is disconnected and that for all integers m, we find all integers a and b such that (9m(2) - 4)a(2) + 4 and 5b(2) +/- 4 are square. It turns out that the set of numbers b comprises ...
Circuit lengths of graphs for the Picard group
(Springer International Publishing Ag, 2013)
In this paper, we examine some properties of suborbital graphs for the Picard group. We obtain edge and circuit conditions, then propose a conjecture for the graph to be forest. This paper is an extension of some results ...
Connectedness of a suborbital graph for congruence subgroups
(Springer International Publishing Ag, 2013)
In this paper, we give necessary and sufficient conditions for the graph to be connected and a forest. MSC: 20H10, 20H05, 05C05, 05C20.
