Plain-language statement

For two distinct forest tops u1,u2u_1,u_2 with nested spatial cubes, and for a comparison cube JJ, the cutoff function χu1,u2,J\chi_{u_1,u_2,J} is Lipschitz on I(u1)\mathcal I(u_1) at the scale of JJ:

d(χ(x),χ(x))C(a)d(x,x)Ds(J).d\bigl(\chi(x),\chi(x')\bigr)\le C(a)\,\frac{d(x,x')}{D^{s(J)}}.
