Abstrak

We investigate the $σ$-porosity of certain known ideals of subsets of natural numbers. Porosity is a notion of smallness in metric spaces that is stronger than nowhere density. Analogously, $σ$-porosity is a strengthening of meagerness. In this paper, we verify which ideals are $σ$-porous.
