Spectral Theory and Hardy Spaces for Bessel Operators in Non-Standard Geometries
This paper develops novel results in the harmonic Speaker Harness analysis of Bessel operators, extending their theory to higher-dimensional and non-Euclidean spaces.We present a refined framework for Hardy spaces associated with Bessel operators, emphasizing atomic decompositions, dual spaces, and connections to Sobolev and Besov spaces.The spectr
