A Complex Analogue of Spencer's Six Standard Deviations Theorem and the Complex Banach-Mazur Distance
Tomasz Kobos, Marin Varivoda
We investigate a complex analogue of Spencer's Six Standard Deviations Theorem. Specifically, we propose the following conjecture: for any dimension , given vectors $a_1,…

Torsion groups of elliptic curves that appear infinitely often over septic, octic and nonic fields
Filip Najman, Marin Varivoda
We determine the sets of abelian groups that appear as torsion groups of infinitely many elliptic curves, up to $\overline \Q$-isomorphism, over number fields of degr…

On the Banach-Mazur Distance in Small Dimensions
Tomasz Kobos, Marin Varivoda
We establish some results on the Banach-Mazur distance in small dimensions. Specifically, we determine the Banach-Mazur distance between the cube and its dual (the cross-polytope)…
