Actual dyadic mass smallness from splitting and the cutoff
- theorem
OAI.RegularPointCoordinates.dyadic_bochner_mass_smallline 20Source documentation
The same full Bochner measure is small relative to the actual heat metric at every sufficiently fine scale. The coefficient depends on the fixed volume and cutoff constants, and is linear in the splitting error.
