Laboratory of Applied Mathematics, Lappeenranta University of Technology, P.O. Box 20, FIN-53851 Lappeenranta, Finland
We applied the theory of Moebius transformations, known in complex analysis, to fuzzy subgroups. We start using the two results presented by B. Seselja and A. Tepavcevic [4,5], taking a topological view point not in these papers. This leads to topological subgroups of a group of Moebius transformations. Although this is known in complex analysis, we approach it through of fuzzy concepts.
