Abstract : We introduce a transformation of time-varying graphs, called Delta-Duplication, that reduces the temporal heterogeneity in the context of dynamic networks analysis. Instead of building a sequence of snapshots from a global time partitioning, we propose a individual-centred approach: we duplicate a vertex for every time periods where the vertex interacts at least every Delta. This short note describes the general theory of Delta-Duplication and provides some directions for applications to dynamic networks analysis. In particular, we introduce a generalization of the concept of k-cores to temporal graphs using this model.
