Endpoint restriction estimates for the paraboloid over finite fields

Allison Lewko, Mark Lewko

We prove certain endpoint restriction estimates for the paraboloid over finite fields in three and higher dimensions. Working in the bilinear setting, we are able to pass from esti…

An Improved Upper Bound for the Sum-free Subset Constant

Mark Lewko

We show that the optimal constant in Erdös' sum-free subset theorem cannot be larger than $11/28 \approx .393$ .

On the Structure of Sets of Large Doubling

Allison Lewko, Mark Lewko

We investigate the structure of finite sets $A \subseteq Z$ where $∣ A + A ∣$ is large. We present a combinatorial construction that serves as a counterexample to natural conjectures…
