On the Number of Discrete Chains

Eyvindur Ari Palsson, Steven Senger, Adam Sheffer

We study a generalization of Erd\H os's unit distances problem to chains of distances. Given a set of points, and a sequence of distances ,…

Sum-Product Phenomena for Planar Hypercomplex Numbers

Matthew Hase-Liu, Adam Sheffer

We study the sum-product problem for the planar hypercomplex numbers: the dual numbers and double numbers. These number systems are similar to the complex numbers, but it turns out…

A Construction for Difference Sets with Local Properties

Sara Fish, Ben Lund, Adam Sheffer

We construct finite sets of real numbers that have a small difference set and strong local properties. In particular, we construct a set of real numbers such that $|A-A|=n^…

Local Properties via Color Energy Graphs and Forbidden Configurations

Sara Fish, Cosmin Pohoata, Adam Sheffer

The local properties problem of Erdős and Shelah generalizes many Ramsey problems and some distinct distances problems. In this work, we derive a variety of new bounds for the loca…

Local Properties in Colored Graphs, Distinct Distances, and Difference Sets

Cosmin Pohoata, Adam Sheffer

We study Extremal Combinatorics problems where local properties are used to derive global properties. That is, we consider a given configuration where every small piece of the conf…

A General Incidence Bound in and Related Problems

Thao Do, Adam Sheffer

We derive a general upper bound for the number of incidences with -dimensional varieties in . The leading term of this new bound generalizes previous bounds for t…
