The geometry of hyperbolic lines in polar spaces
Hans Cuypers
In this paper we consider partial linear spaces induced on the point set of a polar space, but with as lines the hyperbolic lines of this polar space. We give some geometric charac…
On some subgroups of linear groups over generated by elements of order
Hans Cuypers
Let be a vector space over the field of order . We investigate subgroups of the linear group which are generated by a conjugacy class of elements of order su…
A geometric characterization of the symplectic Lie algebra
Hans Cuypers, Yael Fleischmann
A nonzero element in a Lie algebra with Lie product is called extremal if is a multiple of for all . In this paper we characterize the…
A geometric characterization of the classical Lie algebras
Hans Cuypers, Yael Fleischmann
A nonzero element x in a Lie algebra g over a field F with Lie product [ , ] is called a extremal element if [x, [x, g]] is contained in Fx. Long root elements in classical Lie alg…
