Weyl Tensors, Strongly Regular Graphs, Multiplicative Characters, and a Quadratic Matrix Equation
Christopher Deninger, Theo Grundhöfer, Linus Kramer
We study solutions of a quadratic matrix equation arising in Riemannian geometry. Let be a real symmetric -matrix with zeros on the diagonal and let be a real nu…

Unitals with many involutory translations
Theo Grundhöfer, Markus J. Stroppel, Hendrik Van Maldeghem
If every point of a unital is fixed by a non-trivial translation and at least one translation has order two then the unital is classical (i.e., hermitian).

Moufang sets generated by translations in unitals
Theo Grundhöfer, Markus J. Stroppel, Hendrik Van Maldeghem
We consider unitals of order with two points which are centers of translation groups of order . The group generated by these translations induces a Moufang set on the bl…
