• #### A construction of hyperbolic Coxeter groups ﻿

[OWP-2010-04] (Mathematisches Forschungsinstitut Oberwolfach, 2010)
We give a simple construction of Gromov hyperbolic Coxeter groups of arbitrarily large virtual cohomological dimension. Our construction provides new examples of such groups. Using this one can construct e.g. new groups ...
• #### Non-integrated defect relation for meromorphic maps of complete Kähler manifolds into a projective variety intersecting hypersurfaces ﻿

[OWP-2010-19] (Mathematisches Forschungsinstitut Oberwolfach, 2010)
In 1985, Fujimoto established a non-integrated defect relation for meromorphic maps of complete Kähler manifolds into the complex projective space intersecting hyperplanes in general position. In this paper, we generalize ...
• #### A series of algebras generalizing the Octonions and Hurwitz-Radon Identity ﻿

[OWP-2010-10] (Mathematisches Forschungsinstitut Oberwolfach, 2010)
We study non-associative twisted group algebras over $(\mathbb{Z}_2)^n$ with cubic twisting functions. We construct a series of algebras that extend the classical algebra of octonions in the same way as the Clifford algebras ...
• #### Supertropical Matrix Algebra III : Powers of Matrices and Generalized Eigenspaces ﻿

[OWP-2010-20] (Mathematisches Forschungsinstitut Oberwolfach, 2010)
We investigate powers of supertropical matrices, with special attention to the role of the coefficients of the supertropical characteristic polynomial (especially the supertropical trace) in controlling the rank of a power ...
