We present a new $6D$ infinite spin field theory in the light-front formulation. The Lorentz-covariant counterparts of these fields depend on 6-vector coordinates and additional spinor variables. Casimir operators this realization are found. obtain infinite-spin light-cone frame which two sets $\mathrm{SU}(2)$-harmonic generators Poincar\'e group action formulation presented.

Spherical microphone arrays provide a new and promising tool for the spatial analysis of complex sound fields. Most current frameworks, including HOA (Higher Order Ambisonics), rely on the spherical harmonic expansion of the sound field to form directional beams. Working in the spherical harmonic domain presents a number of advantages that include scalability (keeping the low-order components l...

We provide a prescription to compute the gravitational multipole moments of compact objects for asymptotically de Sitter spacetimes. Our builds upon recent definition in terms Noether charges associated specific vector fields, within residual harmonic gauge, dubbed symmetries. first derive symmetries spacetimes which are Sitter; we also show that these symmetry fields eliminate non-propagating ...

The tomographic imaging of vector elds on bounded domains is considered. Reconstruction formulas for the probe transform are rst shown to be valid on bounded domains. It is then shown that potential functions reconstructed from these formulas include a component that arises from the harmonic component of the vector eld, which is due to boundary conditions alone. Closed form expressions for the ...
