Harbourne constants, pull-back clusters and ramified morphisms
Piotr Pokora, Joaquim Roé
We describe the effect of ramified morphisms on Harbourne constants of reduced effective divisors. With this goal, we introduce the pullback of a weighted cluster of infinitely nea…
Hirzebruch-type inequalities viewed as tools in combinatorics
Piotr Pokora
The main purpose of this survey is to provide an introduction, algebro-topological in nature, to Hirzebuch-type inequalities for plane curve arrangements in the complex projective…
Hirzebruch-Kummer covers of algebraic surfaces
Piotr Pokora
The aim of this paper is to show that using some natural curve arrangements in algebraic surfaces and Hirzebruch-Kummer covers one cannot construct new examples of ball-quotients,…
The 21 reducible polars of Klein's quartic
Piotr Pokora, Joaquim Roé
We describe the singularities and related properties of the arrangement of 21 reducible polars of Klein's quartic, containing Klein's well-known arrangement of lines.
