Title: Cardinal invariants related to free sets

Abstract: (Joint work with T. Żuchowski) Given a function \(f\) without fixed points, an infinite set \(A\) is called free for \(f\) if \(f[A] \cap A = \emptyset\). In this talk we will discuss some cardinal invariants related to families of free sets and we will discuss their relation between some cardinal invariants related to category and measure.
