WebApr 10, 2024 · Abstract. A neighbor sum distinguishing (NSD) total coloring ϕ of G is a proper total coloring such that ∑ z ∈ E G ( u) ∪ { u } ϕ ( z) ≠ ∑ z ∈ E G ( v) ∪ { v } ϕ ( z) for each edge u v ∈ E ( G). Pilśniak and Woźniak asserted that each graph with a maximum degree Δ admits an NSD total ( Δ + 3) -coloring in 2015.
