On Newton-Okounkov bodies of Graded Linear Series
Georg Merz
We generalize the theory of Newton-Okounkov bodies of big divisors to the case of graded linear series. One of the results is the generalization of slice formulas and the existence…

On the Mori theory and Newton-Okounkov bodies of Bott-Samelson varieties
Georg Merz, David Schmitz, Henrik Seppänen
We prove that on a Bott-Samelson variety every movable divisor is nef. This enables us to consider Zariski decompositions of effective divisors, which in turn yields a descript…
