Disjoint Representation of Tree Realizable Sequences

SIAM Journal on Applied Mathematics, 1974
A necessary and sufficient condition is obtained for the edge disjoint tree realization of two degree sequences each of which is tree realizable. The condition is that the sum sequence be graphical.

On the status sequences of trees

2018
The status of a vertex v in a connected graph is the sum of the distances from v to all other vertices. The status sequence of a connected graph is the list of the statuses of all the vertices of the graph. In this paper we investigate the status sequences of trees. Particularly, we show that it is NP-complete to decide whether there exists a tree that
