Network Sheaf: Sheaves are algebraic data structures tethered to a topological space. This image captures the network version of this concept, where vector spaces of data float above the nodes of a vertex. Such sheaves can model systems ranging from information dynamics over social networks to interfering signal flows in wireless networks. The algebraic topology of the sheaf, as hinted in the illustration, reflects both the data structure and the inherent notions of local-to-global, where each node can integrate local data into global solutions. The perspective of the illustration emphasizes the vastness and endless possibility of potential uses for sheaves.
