WebSpheric and aspheric designs differ in the curvature of a contact lens. Aspheric lenses showcase varying curvatures across their surface that include a flatter area, unlike … WebOct 18, 2024 · The concept of spherical t -designs, which approximate the whole sphere, was introduced by Delsarte et al [ 14] in 1977. It is well known that spherical t -designs in Sd−1 exist for all t and d which is proved by Seymour–Zaslavsky [ 29 ]. However, the explicit construction of spherical t -designs is in general challenging.

Although some sporadic examples are known, no general construction has been given. In this paper we give an explicit construction of spherical t -designs on S d−1 containing N points, for every t,d and N,N ≥ N 0, where N 0 = C ( d)t O (d 3 ).
