Weighted Weak Type Estimates for Square Functions

Lacey, Michael T · Scurry, James

Original · EN

We consider the weak-type inequality for Littlewood-Paley square functions on Aₚ weighted Lebesgue spaces. Of interest is the sharp in the Aₚ characteristic estimate. The case of 1<p<2 is subcritical, and the sharp power of 1/p is established. In the critical case of p=2, we miss the critical exponent 1/2 by a logarithm of the Aₚ characteristic. These estimates improve on known estimates for 1<p<3.
