Structure of 2-step nilpotent ergodic averages for distinct-degree polynomials

Andreas Koutsogiannis, Borys Kuca, Wenbo Sun

We investigate manifestations of the Nilpotent Heuristic, which posits that recurrence and convergence phenomena known for measure-preserving -systems extend to nilpo…

Partition regularity in imaginary quadratic rings of integers

Sebastián Donoso, Andreu Ferré Moragues, Andreas Koutsogiannis +1

We obtain partition regularity results for homogeneous quadratic equations whose parametrized solutions admit nice factorizations into linear forms over rings of integers of imagin…
