Abstract. Let be the signed edge total domination number of a graph . A fan graph , of order , , is obtain from a path with vertices, denoted , and a single vertex which is adjacent to every vertices of . Let be an cycle. The graph , and , has edges and it consists of the union of copies of with precisely one common edge. In addition, the cycle have exactly two vertices in common. In this paper, we calculate the , and , , .
