Polyhedra, lattice structures, and extensions of semigroups

Klaus Altmann, Alexandru Constantinescu, Matej Filip

For an arbitrary rational polyhedron we consider its decompositions into Minkowski summands and, dual to this, the free extensions of the associated pair of semigroups. Being free…

Klaus Altmann, Frederik Witt

We characterise and investigate co-Higgs sheaves and associated algebraic and combinatorial invariants on toric varieties. In particular, we compute explicit examples.
