Abstract
In this communication, the pathos vertex semi-middle graph of a tree is introduced. Its study is concentrated only on trees. We present a characterization of those graphs whose pathos vertex semi-middle graph of a tree is planar, crossing number one and crossing number two. Also we establish a characterization of graphs whose pathos vertex semi-middle graph of a tree is noneulerian, hamiltonian.
Keywords and Phrases
Crossing number; Middle graph; Planar; Semientire graph.
