A Tarski semigroup is an algebraic system which mirrors a fragment of the additive theory of cardinal numbers. Here we show that any two such systems have the same universal theory. We also give a simple arithmetical necessary and sufficient condition for a universal sentence to hold in a Tarski semigroup.

Sahlqvist via Translation [PDF]
In recent years, unified correspondence has been developed as a generalized Sahlqvist theory which applies uniformly to all signatures of normal and regular (distributive) lattice expansions.

Alfred Tarski frequently declared that his semantic definition of truth was inspired by Aristotle’s views. The present paper discusses this issue in the context of Marian Wesoły’s criticism of the thesis that there is an affinity between Tarski’s views ...

On Implicative and Positive Implicative GE Algebras
GE algebras (generalized exchange algebras), transitive GE algebras (tGE algebras, for short) and aGE algebras (that is, GE algebras verifying the antisymmetry) are a generalization of Hilbert algebras. Here some properties and characterizations of these

Carnap's Contribution to Tarski's Truth.
In his seminal work “The Concept of Truth in Formalized Languages” (1933), Alfred Tarski showed how to construct a formally correct and materially adequate definition of true sentence for certain formalized languages. These results have, eventually, been

Truth and Theories of Truth [PDF]
The concept of truth and competing philosophical theories on what truth amounts to have an important place in contemporary philosophy. The aim of this chapter is to give a synopsis of different theories of truth and the particular philosophical issues ...

Invariance and Logicality in Perspective [PDF]
Although the invariance criterion of logicality first emerged as a criterion of a purely mathematical interest, it has developed into a criterion of considerable linguistic and philosophical interest. In this paper I compare two different perspectives on

LÓGICA MODAL DO OPERADOR DE CONSEQUÊNCIA: HISTÓRICO, REPRESENTAÇÃO POLINOMIAL E DECIDIBILIDADE
Este texto apresenta um breve histórico da lógica TK, originalmente motivada pelo conceito de operador de consequência de Tarski, a sua adequação segundo os Espaços de Tarski e uma caracterização como uma lógica modal não normal.

Tarski monoids: Matui's spatial realization theorem
We introduce a class of inverse monoids, called Tarski monoids, that can be regarded as non-commutative generalizations of the unique countable, atomless Boolean algebra. These inverse monoids are related to a class of etale topological groupoids under a
