    Uncountable Trees and Cohen -Reals.Giorgio Laguzzi - 2019 - Journal of Symbolic Logic 84 (3):877-894.
    We investigate some versions of amoeba for tree-forcings in the generalized Cantor and Baire spaces. This answers [10, Question 3.20] and generalizes a line of research that in the standard case has been studied in [11], [13], and [7]. Moreover, we also answer questions posed in [3] by Friedman, Khomskii, and Kulikov, about the relationships between regularity properties at uncountable cardinals. We show ${\bf{\Sigma }}_1^1$-counterexamples to some regularity properties related to trees without club splitting. In particular we prove a strong (...)

    A Null Ideal for Inaccessibles.Sy-David Friedman & Giorgio Laguzzi - 2017 - Archive for Mathematical Logic 56 (5-6):691-697.

    Some Considerations on Amoeba Forcing Notions.Giorgio Laguzzi - 2014 - Archive for Mathematical Logic 53 (5-6):487-502.
    In this paper we analyse some notions of amoeba for tree forcings. In particular we introduce an amoeba-Silver and prove that it satisfies quasi pure decision but not pure decision. Further we define an amoeba-Sacks and prove that it satisfies the Laver property. We also show some application to regularity properties. We finally present a generalized version of amoeba and discuss some interesting associated questions.

    On the Separation of Regularity Properties of the Reals.Giorgio Laguzzi - 2014 - Archive for Mathematical Logic 53 (7-8):731-747.
    We present a model where ω1 is inaccessible by reals, Silver measurability holds for all sets but Miller and Lebesgue measurability fail for some sets. This contributes to a line of research started by Shelah in the 1980s and more recently continued by Schrittesser and Friedman, regarding the separation of different notions of regularity properties of the real line.
