Porosity properties of perturbed Cantor sets
We study perturbed Cantor subsets of $[0,1]$ which, in the general case, differ in some respects from central Cantor sets. We focus on their porosity properties. We obtain sufficient conditions for a perturbed Cantor set to be porous (or strongly porous). We establish the exact values of upper one-sided porosities at certain points with periodic addresses of special perturbed Cantor sets.
