,Notes on Local Positivity and Newton–Okounkov Bodies,We explore the notion of local numerical equivalence in higher dimension and its relationship with Newton–Okounkov bodies with respect to flags centered at a given point.

,Newton–Okounkov Bodies and Reified Valuations of Higher Rank,We study the shape change of the Newton–Okounkov body of a fixed divisor . with respect to a valuation . moving in a suitable space of (higher-rank) valuations.

,Semigroup and Poincaré Series for Divisorial Valuations,the Poincaré series associated to ., assuming that . has a finite generating sequence. First, if . is infinite, this semigroup is finitely generated. Secondly, for any ., the Poincaré series associated to . is a rational function whose denominator can be expressed in terms of the valuation vectors of the elements in the generating sequence.

On the Containment Hierarchy for Simplicial Ideals,etry. Our considerations are mainly inspired by results of Bocci–Harbourne in (Bocci and Harbourne. Proc. Am. Math. Soc. 138, 1175–1190 (2010) [.]). The results presented on a poster are from (Lampa-Baczyńska and Malara. J. Pure Appl. Algeb. 219, 5402–5412 (2015) [.]), the common paper of both authors.
