On congruence equations arising from suborbital graphs

In this paper we deal with congruence equations arising from suborbital graphs of the normalizer of Gamma(0) (m) in PSL(2, R). We also propose a conjecture concerning the suborbital graphs of the normalizer and the related congruence equations. In order to prove the existence of solution of an equation over prime finite field, this paper utilizes the Fuchsian group action on the upper half plane and Farey graphs properties.C1 [Guler, Bahadir Ozgur] Karadeniz Tech Univ, Fac Sci, Dept Math, Trabzon, Turkey.[Besenk, Murat] Pamukkale Univ, Fac Sci & Letters, Dept Math, Denizli, Turkey.[Kader, Serkan] Omer Halisdemir Univ, Fac Arts & Sci, Dept Math, Nigde, Turkey
