Abstract: We consider cubature formulae which are invariant with respect to a transformation group and prove sufficient conditions for such formulae to have positive weights.
This is worked out for different symmetries: we consider central symmetric, symmetric and fully symmetric cubature formulae.
The theoretical results are illustrated with examples.
