An undirected graph G is called an edge intersection graph of paths in a tree if G=EPT(P) for some P and T. The EPT graphs are useful in network applications.
Theorem 2.2 A graph G is weakly chordal and 1-EPT graph if and only if G has a 1-EPT representation on a degree 4 tree. Proof Sketch: (⇐) Let < P,T > be a 1-EPT ...

This work combines the known notion of the edge intersection graphs of paths in a tree with a VLSI grid layout model and proves that any tree is a B1‐EPG ...
We prove a new analogous result that weakly chordal EPT graphs are precisely the EPT graphs with host tree restricted to degree 4. This also implies that the ...
