Minkowski decomposition and generators of the moving cone for toric varieties
Piotr Pokora, David Schmitz, Stefano Urbinati
We prove that for smooth projective toric varieties, the Okounkov body of a -invariant pseudo-effective divisor with respect to a -invariant flag decomposes as a finite Minko…
A counterexample to the containment over the reals
Adam Czapliński, Agata Główka, Grzegorz Malara +4
The purpose of this note is to give counterexamples to the containment over the real numbers.
Rank Function Equations and their solution sets
Piotr Pokora
We examine so-called rank function equations and their solutions consisting of non-nilpotent matrices. Secondly, we present some geometrical properties of the set of solutions to c…
Points fattening on P^1 x P^1 and symbolic powers of bi-homogeneous ideals
Magdalena Baczyńska, Marcin Dumnicki, Agata Habura +5
We study symbolic powers of bi-homogeneous ideals of points in the Cartesian product of two projective lines and extend to this setting results on the effect of points fattening ob…
