Stack density

Antichain.stack_density

Plain-language statement

Fix a frequency parameter ϑ\vartheta, a level NN, and a spatial grid cube LL. Among the auxiliary tiles attached to an antichain A\mathfrak{A} whose spatial cube is exactly LL, the total measure of their active sets inside GG is at most

2a(N+5)dens1(A)μ(L).2^{a(N+5)}\,\mathrm{dens}_1(\mathfrak{A})\,\mu(L).
