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…

Study of higher-order interactions in unweighted, undirected networks using persistent homology

Udit Raj, Slobodan Maletić, Sudeepto Bhattacharya

Persistent homology has been studied to better understand the structural properties and topology features of weighted networks. It can reveal hidden layers of information about the…

Simplicial structures in ecological networks

Udit Raj, Shashankaditya Upadhyay, Moumita Karmakar +1

An ecological network is a formal representation of a specific type of interaction in a corresponding ecosystem. Such networks have traditionally been modelled as encoding exclusiv…

Higher-order social-ecological network as a simplicial complex

Sudeepto Bhattacharya

A social-ecological network is a formal representation of a corresponding social-ecological system, and encodes a relation within a given system as an interaction. Conventionally,…

Community structures in simplicial complexes: an application to wildlife corridor designing in Central India -- Eastern Ghats landscape complex, India

Saurabh Shanu, Shashankaditya Upadhyay, Arijit Roy +2

The concept of simplicial complex from Algebraic Topology is applied to understand and model the flow of genetic information, processes and organisms between the areas of unimpaire…
