Hodge Operators and Exceptional Isomorphisms between Unitary Groups
Linus Kramer, Markus J. Stroppel
We give a generalization of the Hodge operator to spaces endowed with a hermitian or symmetric bilinear form over arbitrary fields, including the characteristic two cas…
Hodge operators and groups of isometries of diagonalizable symmetric bilinear forms in characteristic two
Linus Kramer, Markus J. Stroppel
We study groups of isometries on non-alternating symmetric bilinear forms on vector spaces of characteristic two, and actions of these groups on exterior powers of the space, viewe…
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).
Finite subunitals of the Hermitian unitals
Theo Grundhöfer, Markus J. Stroppel, Hendrik Van Maldeghem
Every finite subunital of any generalized hermitian unital is itself a hermitian unital; the embedding is given by an embedding of quadratic field extensions. In particular, a gene…
