,Letter to Professor Paul Turán, formal meeting some years ago, gave me the idea of writing humorous obituaries about living people, and although I did not do so, I could have sent you a version of this letter during your life. Almost since I first met you I delighted in turning against you your principles about mathematics, that集聚成团 发表于 2025-3-25 19:38:31

A generalization of ultraspherical polynomials,mula and proving it by induction, is derived in a natural way and some other formulas are obtained. These polynomials generalize zonal spherical harmonics on spheres and include as special cases polynomials that are spherical functions on rank one spaces over reductive .-adic groups. A limiting caseCHIP 发表于 2025-3-26 07:15:20
