摘要

We extend the notion of hyperuniformity to the projective spaces \(\mathbb{R}\mathbb{P}^{d-1}\) R P d - 1 , \(\mathbb{C}\mathbb{P}^{d-1}\) C P d - 1 , \(\mathbb{H}\mathbb{P}^{d-1}\) H P d - 1 , and \(\mathbb{O}\mathbb{P}^2\) O P 2 . We show that hyperuniformity implies uniform distribution and present examples of deterministic point sets as well as point processes which exhibit hyperuniform behaviour.
