Lower Porosity on R2 [PDF]

open access: yesSymmetry, 2021
In this paper, we study the properties of a lower porosity of a set in R2. It turns out that the properties of the lower and upper porosity are symmetrical, except that the main tools for testing the lower porosity are not balls but cones. New families of topologies on R2 generated by the lower porosity are defined.
