A Lie Algebra Method for Rational Parametrization of Severi-Brauer Surfaces
Willem A. de Graaf, Michael Harrison, Jana Pilnikova +1
It is well-known that a Severi-Brauer surface has a rational point if and only if it is isomorphic to the projective plane. Given a Severi-Brauer surface, we study the problem to d…

Classification of solvable Lie algebras
W. A. de Graaf
We illustrate some simple ideas that can be used for obtaining a classification of small-dimensional solvable Lie algebras.Using these we obtain the classification of 3 and 4 dimen…
