Directional spin wavelets on the sphere
Jason D. McEwen, Boris Leistedt, Martin Büttner +2
We construct a directional spin wavelet framework on the sphere by generalising the scalar scale-discretised wavelet transform to signals of arbitrary spin. The resulting framework…
A novel sampling theorem on the rotation group
J. D. McEwen, M. Büttner, B. Leistedt +2
We develop a novel sampling theorem for functions defined on the three-dimensional rotation group SO(3) by connecting the rotation group to the three-torus through a periodic exten…
Analysing the polarisation of the CMB with spin scale-discretised wavelets
Boris Leistedt, Jason D. McEwen, Martin Büttner +3
We discuss a new scale-discretised directional wavelet transform to analyse spin signals defined on the sphere, in particular the polarisation of the cosmic microwave background (C…
