TY - JOUR T1 - Laplacian matrices and Alexandrov topologies of digraphs JF - Linear Algebra and its Applications Y1 - 2015 A1 - Aaron Ostrander KW - Laplacian matrix AB - We explore the spectral properties of digraph Laplacians and how they relate to topological properties of digraphs (such as openness, closure, and strong connectedness) under the Alexandrov topology.
