Gabor frames generated by Random-Periodic time-frequency shifts
Sarthak Raj, S. Sivananthan
In this article, we consider a variation of the existence of Gabor frames in a probabilistic setting, in which we consider time-frequency shifts taken over random-periodic sets. We…

Asymptotic behaviour of massless fields and kinematic duality between interior null cones and null infinity
Xavier Bekaert, S. I. Aadharsh Raj
The relation between two branches of solutions (radiative and subradiative) of wave equations on Minkowski spacetime is investigated, for any integer spin, in flat Bondi coordinate…
