متن کاملDiscrete Analogues of Singular Radon Transforms
The purpose of this paper is to describe recent results we have obtained in finding discrete analogues of the theory of singular integrals on curves, or more generally of "singular Radon transforms," at least in the translation-invariant case. Our theorems are related to estimates for certain exponential sums that arise in number theory; they are also connected with Bourgain's recent maximal er...
متن کاملSingular Radon Transforms and Maximal Functions under Convexity Assumptions
We prove variable coefficient analogues of results in [5] on Hilbert transforms and maximal functions along convex curves in the plane.
متن کاملMulti-linear Generalised Radon Transforms 2
holds for all open sets U ⊆ Σ in a sufficiently small neighbourhood of the origin. We have already seen that (1) holds for non-trivial values of p only if the family Xπ of associated vector fields satisfies the Hörmander condition. A deeper fact is that the converse of this statement is true. This converse may be expressed in a very precise fashion which relates the range of Lebesgue exponents ...
