Community Detection using the Edge Laplacian Dynamics vis-a-vis Ricci Flow
Pratibha Bhandari, Soumyendu Raha
It has been found that utilizing the geometric properties of the graph dynamics can bring out crucial information of the data that a statistical analysis will not. The properties o…
Geometry-Consistent Bayesian Filtering under Structural Model Uncertainty: A Geometric Projection Particle Filter
Surya Ratna Prakash D, Soumyendu Raha
Nonlinear state estimation under structural model uncertainty remains a fundamental challenge in autonomous Guidance, Navigation, and Control (GNC) systems. Conventional Bayesian f…
Co-State Based Data Fusion and Risk Aware Filtering for Spacecraft Navigation and Hazard Prediction
Surya Ratna Prakash D, Soumyendu Raha
This paper develops a co-state based fusion frame work for spacecraft navigation, consistency monitoring, and hazard forecasting. A differential algebraic co-state is introduced as…
A graph based advection framework for climate-driven species distribution
Pranali Roy Chowdhury, Soumyendu Raha
Climate change is reshaping species interactions and movement across fragmented landscapes. Despite this, most mathematical models assume random diffusion, overlooking the influenc…
Transient Stability of Nonlinear Stochastic Dynamics: A Finite-Amplitude Logarithmic Measure Framework
Surya Ratna Prakash D, Soumyendu Raha
Spacecraft guidance, navigation, and control systems operating during mission-critical phases such as atmospheric entry, powered descent, and planetary landing require reliable ass…
