"Big cone decompositions and volume of chambers"

Abstact
I will recall some decompositions of the big cone of a smooth projective variety in terms of the mapping behavior of linear series and study their geometric properties. Furthermore, I will introduce a metric description of these decompositions and present effective results in the case of the Zariski chamber decomposition on surfaces introduced by Bauer, Küronya, Szemberg.
