Streszczenie

We provide off-diagonal estimates for maximal operators arising from a geometric problem of estimating the size of a certain geometric configuration of $k$-skeletons in $\mathbb {R}^n$. This is achieved by interpolating a weak-type endpoint estimate with the known diagonal bounds. The endpoint estimate is proved by combining a geometric result about $k$-skeletons and adapting an argument used to prove off-diagonal estimates for the circular maximal function in the plane.
