Domination integrity of total graphs
(Işık University Press, 20131012)The domination integrity of a simple connected graph G is a measure of vulnerability of a graph. Here we determine the domination integrity of total graphs of path Pn, cycle Cn and star K1,n. 
Harmonic mappings related to the convex functions
