On the finite generation of valuation semigroups on toric surfaces
Klaus Altmann, Christian Haase, Alex Küronya +2
We provide a combinatorial criterion for the finite generation of a valuation semigroup associated with an ample divisor on a smooth toric surface and a non-toric valuation of maxi…

Toric Newton-Okounkov functions with an application to the rationality of certain Seshadri constants on surfaces
Christian Haase, Alex Küronya, Lena Walter
We initiate a combinatorial study of Newton-Okounkov functions on toric varieties with an eye on the rationality of asymptotic invariants of line bundles. In the course of our effo…
