Bilinear maximal functions associated with degenerate surfaces

Sanghyuk Lee, Kalachand Shuin

We study -boundedness of (sub)bilinear maximal functions associated with degenerate hypersurfaces. First, we obtain the maximal bound on the sha…

Remarks on dimension of unions of curves

Seheon Ham, Hyerim Ko, Sanghyuk Lee +1

We study an analogue of Marstrand's circle packing problem for curves in higher dimensions. We consider collections of curves which are generated by translation and dilation of a c…

Pointwise convergence of sequential Schrödinger means

Chu-Hee Cho, Hyerim Ko, Youngwoo Koh +1

We study pointwise convergence of the fractional Schrödinger means along sequences which converge to zero. Our main result is that bounds on the maximal function $\sup_{n} |e…
