TOPDRIM partner Francesco Vaccarino and his colleagues jut published in PLOS.One a paper entitled Topological Strata of Weighted Complex Networks where they tackle the mesoscopic structure of complex networks, and where they introduce a novel method, based on persistent homology, to detect particular non-local structures, akin to weighted holes within the link-weight network fabric, which are invisible to existing methods.

Their research is of most importance as this new method creates the first bridge between network theory and algebraic topology, which will allow to import the toolset of algebraic methods to complex systems.
