A note on restricted X-ray transforms
Norberto Laghi
We show how the techniques introduces by Christ can be employed to derive endpoint bounds for the X-ray transform associated to the line complex generated by the curve $t…
Strongly singular integrals along curves
Norberto Laghi, Neil lyall
In this article we obtain bounds for strongly singular integrals along curves in our results both generalise and extend to higher dimensions those obtained by Chandar…
Strongly singular integral operators associated to different quasi-norms on the Heisenberg group
Norberto Laghi, Neil Lyall
In this article we study the behavior of strongly singular integrals associated to three different, albeit equivalent, quasi-norms on Heisenberg groups; these quasi-norms give rise…
Strongly singular Radon transforms on the Heisenberg group and folding singularities
Norberto Laghi, Neil Lyall
We prove sharp regularity results for classes of strongly singular Radon transfoms on the Heisenberg group by means of oscillatory integrals. We show that the problem in ques…
