Abstract
|
We determine the order of magnitude of the
-th
-polarization constant
of the unit sphere
for every
and
.
For
,
we prove that extremizers are isotropic vector sets, whereas for
, we show that
the polarization problem is equivalent to that of maximizing the norm of signed vector sums.
Finally, for
,
we discuss the optimality of equally spaced configurations on the unit circle.
