Nearest Graph Laplacians with Prescribed Connected Components: A Convex Framework for Network Reconstruction

Udit Raj, Sudeepto Bhattacharya, Prince Kanhya

We study the problem of constructing the nearest graph Laplacian matrix to a given Laplacian while enforcing a prescribed connected-component structure. Let the vertex set be parti…

Combinatorial metaplexes and centrality indices for identifying higher-order interactions

Hiren J. Dhameliya, Udit Raj, Sudeepto Bhattacharya

Complex systems consist of interacting units whose interactions may be pairwise, involving two units, or higher-order, involving more than two units simultaneously. Graphs capture…
