    Undecidability of the Real‐Algebraic Structure of Scott's Model
    Mathematical Logic Quarterly 44 (3): 344-348. 2006.
    We show that true first‐order arithmetic of the positive integers is interpretable over the real‐algebraic structure of Scott's topological model for intuitionistic analysis. From this the undecidability of the structure follows.

    Based on the paper [4] we show that true second‐order arithmetic is interpretable over the real‐algebraic structure of models of intuitionistic analysis built upon a certain class of complete Heyting algebras.

    Decidability of Scott's Model as an Ordered $\mathbb{Q}$-Vectorspace
    Journal of Symbolic Logic 62 (3): 917-924. 1997.
    Let $L = \langle, +, h_q, 1\rangle_{q \in \mathbb{Q}}$ where $\mathbb{Q}$ is the set of rational numbers and $h_q$ is a one-place function symbol corresponding to multiplication by $q$. Then the $L$-theory of Scott's model for intuitionistic analysis is decidable.

    We show that true first-order arithmetic is interpretable over the real-algebraic structure of models of intuitionistic analysis built upon a certain class of complete Heyting algebras. From this the undecidability of the structures follows. We also show that Scott's model is equivalent to true second-order arithmetic. In the appendix we argue that undecidability on the language of ordered rings follows from intuitionistically plausible properties of the real numbers.

    Hungarian Language and Law: Developing a Grammar for Social Inclusion, a Vocabulary for Political Emancipation. Special Issue (IJSL)—Editorial Preface
    with Edina Vinnai and Mate Paksy
    International Journal for the Semiotics of Law - Revue Internationale de Sémiotique Juridique 33 (3): 707-727. 2020.
    Having been invited by editor-in-chief, Professor Anne Wagner, to edit the present special issue, we decided to fulfil a longstanding wish to provide a panorama about the Hungarian Language and Law. Along with other ‘law and …’ movements, Law and Language has attracted a great deal of attention from subsequent generations of Hungarian academic lawyers, because the political transition served as a wonderful subject and context for scholarly papers and text books, for examining the putative or rea…Read more
