ABSTRACT
Connectivity is an important measure to explore the fault tolerance and reliability of the network structure based on a graph model. Let be a connected graph. A r-component cut of G is a set S of vertices, G−S has at least r components. The r-component connectivity of G is the size of the smallest r-component cut. The r-component edge connectivity can be defined similarly. In this paper, we determine the r-component connectivity of Cayley graphs generated by transposition trees for and ; we also obtain the r-component edge connectivity of Cayley graphs generated by transposition trees for small r and the upper and lower bounds of for and .
