Pressure-gradient slots at the two endgame instances #
The initial bootstrap and final pressure steps use two fixed triples of Morrey exponent and radii. The actual-integral slots are required only at those triples, above one absolute Calderón–Zygmund threshold.
The two actual-integral slots at the prescribed exponent/radius triples produce the affine pressure-gradient estimate at those same triples.
The small-data conclusion from the actual-integral slots at the two triples used by the bootstrap and final pressure steps. The absolute coefficient also absorbs the singly centred Calderón–Zygmund constant.
Combine the independent absolute cell and time-mass thresholds with the singly centred Calderón–Zygmund constant. Their maximum is nonnegative without any additional hypothesis. Repeating the maximum with the Calderón–Zygmund constant in the common-threshold theorem leaves it unchanged.
