This study aims to describe the algebraic reasoning of students with logical-mathematical Intelligence and visual-spatial Intelligence  in solving algebraic problems. This research is a qualitative descriptive study. The subjects of this study were s... see more

We characterize the non-trivial substructural logics having the variable sharing property as well as its strong version. To this end, we find the algebraic counterparts over varieties of these logical properties.

Tarski presented his definition of consequence operator to explain the most important notions which any logical consequence concept must contemplate. A Tarski space is a pair constituted by a nonempty set and a consequence operator. This structure charact... see more

This study presents some fundamental aspects of recent theories  on algebraic Hyperstructures, an important tool for an interdisciplinary vision of Geometry and Algebra. We examine some hypergroupoids of events, useful for a new algebraic-geometry pe... see more

The sole purpose of this paper is to give an algebraic characterization, in terms of a superamalgamation property, of a local version of Craig interpolation theorem that has been introduced and studied in earlier papers. We continue ongoing research in ab... see more

Context. The development and aplication of cryptographic algorithms based on many-valued logic functions makes it importantto research their cryptographic properties and develop effective criteria for the cryptographic quality of their components. Thedeve... see more

This work adapts techniques and results first developed by Malinowski and by Marek in the context of referential semantics of sentential logics to the context of logics formalized as p-institutions. More precisely, the notion of a pseudoreferential matrix... see more

Babenyshev and Martins proved that two hidden multi-sorted deductive systems are deductively equivalent if and only if there exists an isomorphism between their corresponding lattices of theories that commutes with substitutions. We show that the p-instit... see more

We present in the paper a very concise but updated survey emphasizing the research done by Gr. C. Moisil and his school in algebraic logic.
