Algebraic semantics for predicate logics and their completeness

... Algebraic semantics for nonclassical propositional logics provides us a powerful tool in studying logical properties which are common among many logics. In fact, it has been producing a lot of interesting general results by the help of universal algebraic methods. On the other hand, it seems that th ...

Behavioral Algebraization of Logics

... equality of two hidden values. Hence, equational logic needs to be replaced by behavioral equational logic (sometimes called hidden equational logic) based on the notion of behavioral equivalence. Two values are said to behaviorally equivalent if they cannot be distinguished by the set of all experi ...

Hovhannes Khudaverdian's notes

... In 1824 Abel proved that there is no formula expressing roots of polynomial equation of the order n ≥ 5 in terms of coefficients and a finite number of arithmetical operations ”+”, ”-”, ”×”, ”:” and n-th roots. But what about a given polynomial equation of the order n ≥ 5 Abel Theorem states that ro ...
