Title: Possible modifications of Lusin analytic set

Abstract: In the last talk we breathly mentioned an example of a complete analytic set created by Lusin. This time we will prove that it is a complete analytic set, which is not an element of \(Bor[K_\sigma]\). Then we will investigate some possible modifications of this example in order to decide, which partial orders make this set complete analytic.
