Lie group valued Koopman eigenfunctions
Suddhasattwa Das
Every continuous-time flow on a topological space has associated to it a Koopman operator, which operates by time-shifts on various spaces of functions, such as , , or fu…

Reproducing kernel Hilbert space compactification of unitary evolution groups
Dimitrios Giannakis, Suddhasattwa Das, Joanna Slawinska
A framework for coherent pattern extraction and prediction of observables of measure-preserving, ergodic dynamical systems with both atomic and continuous spectral components is de…

Koopman spectra in reproducing kernel Hilbert spaces
Suddhasattwa Das, Dimitrios Giannakis
Every invertible, measure-preserving dynamical system induces a Koopman operator, which is a linear, unitary evolution operator acting on the space of observables associated…
