# Decay Centrality

#### Definition

Decay centrality is a
centrality measure based on the proximity between a choosen vertex and
every other vertex weighted by the decay. More precisely, decay centrality
of a given vertex x of a graph G is define as:
where d(x, y) denotes the distance between x and y and δ ∈ (0, 1) is a parameter.
