A. Carbery et al., L(P) ESTIMATES FOR OPERATORS ASSOCIATED TO FLAT CURVES WITHOUT THE FOURIER-TRANSFORM, Pacific journal of mathematics, 167(2), 1995, pp. 243-262
The purpose of this paper is to provide new proofs to known theorems o
n the L(p) boundedness of the maximal function and Hilbert transform c
orresponding to curves in R(n) which are ''infinitely flat'' at the or
igin. The old proofs use the Fourier transform in a crucial way. The p
resent proofs avoid the Fourier transform and hence at least have the
potential of being used in more general situations.
