Smoothing of Quiver Varieties
Klaus Altmann, Duco van Straten
We show that Gorenstein singularities that are cones over singular Fano varieties provided by so-called flag quivers are smoothable in codimension three. Moreover, we give a precis…

A fansy divisor on M_{0,n}
Klaus Altmann, Georg Hein
We study the relation between projective T-varieties and their affine cones in the language of the so-called divisorial fans and polyhedral divisors. As an application, we present…

Gluing affine torus actions via divisorial fans
Klaus Altmann, Juergen Hausen, Hendrik Suess
Generalizing the passage from a fan to a toric variety, we provide a combinatorial approach to construct arbitrary effective torus actions on normal, algebraic varieties. Based on…
