Harmonic Analysis on the Unit Ball, however, that analysis on the unit ball is closely related to analysis on the unit sphere. Indeed, a large portion of harmonic analysis on the unit ball can be deduced from its counterparts on the sphere.

Harmonic Analysis Associated with Reflection Groups,ighted approximation and harmonic analysis on the sphere, which turn out to be indispensable for the corresponding theory, even for unweighted approximation and harmonic analysis, on the unit ball and on the simplex, as will be seen in later chapters.

https://doi.org/10.1007/978-3-662-32547-6the Poisson integrals for the Fourier expansion in spherical harmonics, discussed in the second section, are convolution operators, which are also multiplier operators. The convolution and translation operators are used to define and study the Hardy–Littlewood maximal function on the sphere in the third section.

Zeitschrift für die gesamte Anatomiech results for .-harmonic expansions with respect to the product ., which cover results for ordinary spherical harmonic expansions. The proof of such results depends on the boundedness of proj ection operators, which will be established in the first section, assuming a critical estimate.
