In graph theory, an adjacent vertex of a vertex v in a graph is a vertex that is connected to v by an edge. The neighbourhood of a vertex v in a graph G is the subgraph of G induced by all vertices adjacent to v, i.e., the graph composed of the vertices adjacent to v and all edges connecting vertices adjacent to v. The neighbourhood is often denoted or (when the graph is unambiguous) . Th… hud and foreclosed homes

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.
