On Generalized --Vectors of Rational Polytopes with a Symmetry of Prime Order
A. A'Campo-Neuen
We prove tight lower bounds for the coefficients of the generalized -vector of a rational polytope with a symmetry of prime order that is fixed--point--free on the boundary. The…

Quotients of Toric Varieties by the Action of a Subtorus
A. A'Campo-Neuen, J. Hausen
We consider the action of a subtorus of the big torus on a toric variety. The aim of the paper is to define a natural notion of a quotient for this setting and to give an explicit…

Quasi--Projective Reduction of Toric Varieties
A. A'Campo-Neuen, J. Hausen
We define a quasi--projective reduction of a complex algebraic variety to be a regular map from to a quasi--projective variety that is universal with respect to regular map…
