Porosities of the sets of attractors
Paweł Klinga, Adam Kwela
This paper is another attempt to measure the difference between the family of attractors for iterated function systems acting on and a broader family, the set $A_w…
Comparison of the sets of attractors for systems of contractions and weak contractions
Paweł Klinga, Adam Kwela
For we consider the families: - of attractors for iterated function systems (IFS) consisting of contractions acting on , - of attra…
Borel complexity of the family of attractors for weak IFSs
Paweł Klinga, Adam Kwela
This paper is an attempt to measure the difference between the family of iterated function systems attractors and a broader family, the set of attractors for weak iterated function…
On a conjecture of Debs and Saint Raymond
Adam Kwela
Borel separation rank of an analytic ideal on is the minimal ordinal such that there is with $\mathcal{I}\subseteq \mathc…
On extendability to ideals
Adam Kwela
Answering in negative a question of M. Hrušák, we construct a Borel ideal not extendable to any ideal and such that it is not Katětov above the ideal .
Inductive limits of ideals
Adam Kwela
G. Debs and J. Saint Raymond in 2009 defined the Borel separation rank of an analytic ideal () as minimal ordinal such that there is…
Unboring ideals
Adam Kwela
Our main object of interest is the following notion: we say that a topological space space is in FinBW(), where is an ideal on , if for each seque…
