A nonabelian Fourier transform for tempered unipotent representations, II
Anne-Marie Aubert, Dan Ciubotaru, Beth Romano
We extend the construction of the nonabelian Fourier transform proposed in our previous paper from the space of unipotent elliptic characters to the space of unipotent compact char…

Families of curves in Vinberg representations
Jef Laga, Beth Romano
Inspired by orbit parametrizations in arithmetic statistics, we explain how to construct families of curves associated to certain nilpotent elements in -gra…

An LLL algorithm with symmetries
Beth Romano, Jack A. Thorne
We give a generalisation of the Lenstra-Lenstra-Lovász (LLL) lattice-reduction algorithm that is valid for an arbitrary (split, semisimple) reductive group . This can be regard…
