Relative projective group codes over chain rings
Simon Eisenbarth, Sihuang Hu
A structure theorem of the group codes which are relative projective for the subgroup of is given. With this, we show that all such relative projective grou…

Spherical 2-designs and lattices from Abelian groups
Albrecht Boettcher, Simon Eisenbarth, Lenny Fukshansky +2
We consider lattices generated by finite Abelian groups. We prove that such a lattice is strongly eutactic, which means the normalized minimal vectors of the lattice form a spheric…
