Abstract :
A graph G is χ-excellent if for every vertex v, there exists a chromatic partition π such that {v} ∈ π.A graph G is just χ-excellent if every vertex appears as a
singleton in exactly one χ-partition. In this paper, a special type of just χ-excellence
namely tight just χ-excellence is defined and studied.
