Abstract
For \(d \geqslant 2,\) we consider asymptotically equidistributed sequences of \(\mathbb S^d\) codes, with an upper bound \(\operatorname{\boldsymbol{\delta}}\) on spherical cap discrepancy, and a lower bound Δ on separation. For such sequences, if 0 < s < d, then the difference between the normalized Riesz s energy of each code, and the normalized s-energy double integral on the sphere is bounded above by \(\operatorname{O}\big(\operatorname{\boldsymbol{\delta}}^{1-s/d}\,\Delta^{-s}\,N^{-s/d}\big),\) where N is the number of code points. For well separated sequences of spherical codes, this bound becomes \(\operatorname{O}\big(\operatorname{\boldsymbol{\delta}}^{1-s/d}\big).\) We apply these bounds to minimum energy sequences, sequences of well separated spherical designs, sequences of extremal fundamental systems, and sequences of equal area points.
