Let G= (V, E) be a graph without isolated vertices. A setS⊂Vis apaired-dominatingset if it dominatesVand the subgraph induced by S,, contains a perfect matching. The paired-domination number γp(G) is defined to be the minimum cardinality of a paired-dominating setSinG. In this paper, we present a linear-time algorithm computing the paired-domination number for trees and characterize trees with equal domination and paired-domination numbers.
