Abstract:

We construct symmetric cubature formulae of degrees in the 13-39 range for the surface measure on the unit sphere. We exploit a recently published correspondence between cubature formulae on the sphere and on the triangle. Specifically, a fully symmetric cubature formula for the surface measure on the unit sphere corresponds to a symmetric cubature formula for the triangle with weight function $(u_{1}u_{2}u_{3})^{-1/2}$, where $u_{1}$, $u_{2}$, and $u_{3}$ are homogeneous coordinates.
