T1 testing implies Tp polynomial testing: optimal cancellation conditions for CZO's
Eric T. Sawyer
Abstrak
This paper is the third in an investigation begun in arXiv:1906.05602 and arXiv:1907.07571 of extending the T1 theorem of David and Journé, and optimal cancellation conditions, to more general weight pairs. The main result here is that the familiar T1 testing conditions over indicators of cubes, together with the one-tailed A2 conditions, imply polynomial testing. Analogous results for fractional singular integrals hold as well. Applications include a T1 theorem for fractional CZO's T in the case of doubling measures when one of the weights is A infinity, and then to optimal cancellation conditions for such CZO's in similar situations.
