$L^{p}$ -estimates for FIO-cone multipliers

Stefan Buschenhenke, Spyridon Dendrinos, Isroil A. Ikromov +1

The classical cone multipliers are Fourier multiplier operators which localize to narrow $1/ R$ -neighborhoods of the truncated light cone in frequency space. By composing such convo…

Some subcritical estimates for the $ℓ^{p}$ -improving problem for discrete curves

Spyridon Dendrinos, Kevin Hughes, Marco Vitturi

We apply Christ's method of refinements to the $ℓ^{p}$ -improving problem for discrete averages $A_{N}$ along polynomial curves in $Z^{d}$ . Combined with certain ele…

Uniform bounds for convolution and restricted X-ray transforms along degenerate curves

Spyridon Dendrinos, Betsy Stovall

We establish endpoint Lebesgue space bounds for convolution and restricted X-ray transforms along curves satisfying fairly minimal differentiability hypotheses, with affine and Euc…
