The CUNY Data Science and Applied Topology Reading Group is joint between the Mathematics and Computer Science programmes. We meet Fridays 11.45 -- 12.45 in GC 3209. You can contact us at cunygc@appliedtopology.nyc.

Our plan is to primarily read and discuss seminal papers in data science, in applied topology and in topological data analysis. Each seminar one participant takes the responsibility to present a paper and prepare items for discussion. We expect occasionally to be able to invite external speakers.

### The Fuglede conjecture holds in the finite vector space \(\mathbb{Z}_p^2\)

We will see that the Fuglede Conjecture holds in $\mathbb{Z}_p^2$, proved by Iosevich/Mayeli/Pakianathan. That is the subsets E of the finite vector space $\mathbb{Z}_p^2$ tiles the space if and only if every function from E to the complex numbers is a linear combination of orthogonal exponential functions. Key ideas of the proof use Fourier transforms of functions from this space, direction sets, and some Galois theory.
