Spectral Koopman Approach for Reconstructing State-space Geometry of Cislunar Restricted 3-Body Problem
Subhrajit Sinha, Sriram S. K. S. Narayanan, Raktim Bhattacharya +1
In this work, we propose a novel approach, based on the path integral formulation of Koopman spectrum, to discover the phase-space geometry of the planar Cislunar Restricted 3 Body…

Linear Systems as Representations of Time Groups
Subhrajit Sinha
In this paper, we develop a representation-theoretic formulation of discrete-time linear systems. We show that such systems are naturally viewed as representations of time groups a…
