Distributed Harmonic-Covariance Feedback for Hole Closure in Planar Robot Swarms

Jitian Liu, Subhrajit Bhattacharya

We consider hole closure in a planar multi-agent system whose sensing disks form a time-varying Čech complex. We propose a harmonic-covariance feedback that uses harmonic edge sign…

From Ellipsoids to Midair Control of Dynamic Hitches

Jiawei Xu, Subhrajit Bhattacharya, David Saldaña

The ability to manipulate and interlace cables using aerial vehicles can greatly improve aerial transportation tasks. Such interlacing cables create hitches by winding two or more…

Distributed Optimization of Bivariate Polynomial Graph Spectral Functions via Subgraph Optimization

Jitian Liu, Nicolas Kozachuk, Subhrajit Bhattacharya

We study distributed optimization of finite-degree polynomial Laplacian spectral objectives under fixed topology and a global weight budget, targeting the collective behavior of th…

Trace of Multi-variable Matrix Functions and its Application to Functions of Graph Spectrum

Subhrajit Bhattacharya

Matrix extension of a scalar function of a single variable is well-studied in literature. Of particular interest is the trace of such functions. It is known that for diagonalizable…

Spectrum Optimization of Dynamic Networks for Reduction of Vulnerability Against Adversarial Resonance Attacks

Alp Sahin, Nicolas Kozachuk, Rick S. Blum +1

Resonance is a well-known phenomenon that happens in systems with second order dynamics. In this paper we address the fundamental question of making a network robust to signal bein…

Weighted Combinatorial Laplacian and its Application to Coverage Repair in Sensor Networks

Shunsaku Yadokoro, Subhrajit Bhattacharya

We define the weighted combinatorial Laplacian operators on a simplicial complex and investigate their spectral properties. Eigenvalues close to zero and the corresponding eigenvec…
