    Integration of Monomials over the Unit Sphere and Unit Ball in Rn

    Calixto P. Calderón; Alberto Torchinsky

    Selecciones Matemáticas, Vol. 12 No. 01 · 2025 · Portugis · DOAJ

    We compute the integral of monomials of the form x2β over the unit sphere and the unit ball in Rn where β = (β1, . . . , βn) is a multi–index with real components βk > −1/2, 1 ≤ k ≤ n, and discuss their asymptotic behavior as some, or all, βk → ∞. This allows for the evaluation of integrals…
