    Applications of the Ergodic Iteration Theorem.Jindřich Zapletal - 2010 - Mathematical Logic Quarterly 56 (2):116-125.
    I prove several natural preservation theorems for the countable support iteration. This solves a question of Rosłanowski regarding the preservation of localization properties and greatly simplifies the proofs in the area.

    Canonical Models for ℵ1-Combinatorics.Saharon Shelah & Jindr̆ich Zapletal - 1999 - Annals of Pure and Applied Logic 98 (1-3):217-259.
    We define the property of Π2-compactness of a statement Φ of set theory, meaning roughly that the hard core of the impact of Φ on combinatorics of 1 can be isolated in a canonical model for the statement Φ. We show that the following statements are Π2-compact: “dominating NUMBER = 1,” “cofinality of the meager IDEAL = 1”, “cofinality of the null IDEAL = 1”, “bounding NUMBER = 1”, existence of various types of Souslin trees and variations on uniformity of (...)

    Increasing $\delta _{2}^{1}$ and Namba-Style Forcing.Richard Ketchersid, Paul Larson & Jindřich Zapletal - 2007 - Journal of Symbolic Logic 72 (4):1372 - 1378.
    We isolate a forcing which increases the value of $\delta _{2}^{1}$ while preserving ω₁ under the assumption that there is a precipitous ideal on ω₁ and a measurable cardinal.

    Semi-Cohen Boolean Algebras.Bohuslav Balcar, Thomas Jech & Jindřich Zapletal - 1997 - Annals of Pure and Applied Logic 87 (3):187-208.
    We investigate classes of Boolean algebras related to the notion of forcing that adds Cohen reals. A Cohen algebra is a Boolean algebra that is dense in the completion of a free Boolean algebra. We introduce and study generalizations of Cohen algebras: semi-Cohen algebras, pseudo-Cohen algebras and potentially Cohen algebras. These classes of Boolean algebras are closed under completion.

Viel weniger Arbeiten haben sich der Analyse geteilter Stimmungen und Emotionen gewidmet. Dies ist nicht nur deshalb bedauerlich, weil das Teilen von (...)

    Terminal Notions in Set Theory.Jindřich Zapletal - 2001 - Annals of Pure and Applied Logic 109 (1-2):89-116.
    In mathematical practice certain formulas φ are believed to essentially decide all other natural properties of the object x. The purpose of this paper is to exactly quantify such a belief for four formulas φ, namely “x is a Ramsey ultrafilter”, “x is a free Souslin tree”, “x is an extendible strong Lusin set” and “x is a good diamond sequence”.

    Certain separation problems in descriptive set theory correspond to a forcing preservation property, with a fusion type infinite game associated to it. As an application, it is consistent with the axioms of set theory that the circle.

  23. Splitting Number at Uncountable Cardinals.Jindřich Zapletal - 1997 - Journal of Symbolic Logic 62 (1):35-42.
    We study a generalization of the splitting number s to uncountable cardinals. We prove that $\mathfrak{s}(\kappa) > \kappa^+$ for a regular uncountable cardinal κ implies the existence of inner models with measurables of high Mitchell order. We prove that the assumption $\mathfrak{s}(\aleph_\omega) > \aleph_{\omega + 1}$ has a considerable large cardinal strength as well.

    The cut and choose game is one of the infinitary games on a complete Boolean algebra B introduced by Jech. We prove that existence of a winning strategy for II in implies semiproperness of B. If the existence of a supercompact cardinal is consistent then so is “for every 1-distributive algebra B II has a winning strategy in ”.

    Hypergraphs and Proper Forcing.Jindřich Zapletal - 2019 - Journal of Mathematical Logic 19 (2):1950007.
    Given a Polish space X and a countable collection of analytic hypergraphs on X, I consider the σ-ideal generated by Borel anticliques for the hypergraphs in the family. It turns out that many of the quotient posets are proper. I investigate the forcing properties of these posets, certain natural operations on them, and prove some related dichotomies.

    Analytic Equivalence Relations and the Forcing Method.Jindřich Zapletal - 2013 - Bulletin of Symbolic Logic 19 (4):473-490.
    I describe several ways in which forcing arguments can be used to yield clean and conceptual proofs of nonreducibility, ergodicity and other results in the theory of analytic equivalence relations. In particular, I present simple Borel equivalence relationsE, Fsuch that a natural proof of nonreducibility ofEtoFuses the independence of the Singular Cardinal Hypothesis at ℵω.

    Forcing Properties of Ideals of Closed Sets.Marcin Sabok & Jindřich Zapletal - 2011 - Journal of Symbolic Logic 76 (3):1075 - 1095.
    With every σ-ideal I on a Polish space we associate the σ-ideal I* generated by the closed sets in I. We study the forcing notions of Borel sets modulo the respective σ-ideals I and I* and find connections between their forcing properties. To this end, we associate to a σ-ideal on a Polish space an ideal on a countable set and show how forcing properties of the forcing depend on combinatorial properties of the ideal. We also study the 1—1 or (...)

    Was genau ist eigentlich eine Ich-Störung? Ich werde auf den folgenden Seiten dafür argumentieren, daß man die Natur dieses Typs von psychiatrischen Störungsbildern besser verstehen kann, indem man einen Blick über die medizinischen Fachgrenzen hinweg in die analytische Philosophie des Geistes [1] und in die Kognitionswissenschaft [2] wirft. Beiden Disziplinen ist gemeinsam, daß mentale Zustände dort häufig einer funktionalen Analyse unterzogen und als Informationsverarbeitungsereignisse beschrieben werden. Das bedeutet, daß mentale Zustände dabei zunächst mit Blick auf die kausale Rolle untersucht werden, (...)

Leipzig, Deutschland: Leipziger Universitätsverlag. pp. 225-270.
    Kein Hahn kräht mehr nach dem Verifikationsprinzip, das Moritz Schlick zusammen mit seinen Mitstreitern des Wiener Kreises verfochten hat. Seit einem halben Jahrhundert gilt das Prinzip als philosophisch erledigt; doch Totgesagte leben länger. Ich versuche, eine Fassung des Prinzips zu formulieren, die auch unter den Bedingungen der Nachkriegs-Philosophie verteidigt werden kann: Grob gesagt, muss jeder sinnvolle Satz im Prinzip empirisch (oder doch aposteriori) überprüft werden können, einerlei ob verifiziert oder falsifiziert, ob fallibel oder infallibel, ob direkt oder indirekt, ob deduktiv, (...)

    Moritz Schlicks Plädoyer für ein empirisches Fundament unserer Erkenntnis enthält weder reduktionistische noch phänomenalistische Extrempositionen. Seine Beispiele für Fundamentalsätze haben allesamt die Form: Hier jetzt so und so; aber nicht alle diese Sätze sind Fundamentalsätze. Was muss man für die letzten drei Wörter dieses Schemas einsetzen, um wirklich beim Fundament anzukommen? Ich schlage vor, die Frage durch Rückgriff auf das interpretationstheoretische Prinzip des Wohlwollens zu beantworten. Demzufolge sind diejenigen Sätze (der Form Hier jetzt so und so) Fundamentalsätze, über die kein (...)
