On Rubio de Francia's maximal theorem

Seheon Ham, Jiwon Kah, Sanghyuk Lee +1

In his influential 1986 paper, Rubio de Francia established $L^{p}$ bounds for the maximal function generated by dilations of measures $I^¼$ whose Fourier transforms $I^¼$ sati…

Local smoothing and maximal estimates for average over surfaces of codimension 2 in $R^{4}$

Seheon Ham, Hyerim Ko

In this paper, we obtain local smoothing estimates for the averages over nondegenerate surfaces of codimension $2$ in $R^{4}$ . We make use of multilinear restriction estimate…
