《Finite Element Methods for Maxwell's Equations》 · 第 43 页 · Section 5.5「The Sieve Dimension」
The important parameter $\kappa$ depends on both the density function $g$ and the sifting set of primes $\mathcal P$. For a sequence $\mathcal A$ with density function $g$ it encapsulates in a single number the size of the sifting set of primes and the susceptibility of elements of $\mathcal A$ to being divisible by those primes. We shall take one of its names in the literature and call $\kappa$ the sieve dimension.
