Complexity Issues in Axiomatic Extensions of Lukasiewicz Logic

In this article, the computational complexity of all axiomatic extensions of Lukasiewicz propositional logic L and the arithmetical complexity of both the general and standard semantics of their corresponding predicate ...

Admissible Rules of Lukasiewicz Logic

We investigate admissible rules of Lukasiewicz multi-valued propositional logic. We show that admissibility of multiple-conclusion rules in Lukasiewicz logic, as well as validity of universal sentences in ...

States in Lukasiewicz logic correspond to probabilities of rational polyhedra

It will be shown that probabilities of infinite-valued events represented by formulas in Lukasiewicz propositional logic are in one-to-one correspondence with tight probability measures over rational polyhedra in the unit h...

On the Complexity of Validity Degrees in Łukasiewicz Logic

the range of results by looking at validity degree in propositional Lukasiewicz logicLukasiewicz logic is an established formal system of manyvalued logic. Decision problems in both propositi...

Rough approximations in algebras of a non-associative generalization of the Lukasiewicz infinite valued logic

Commutative basic algebras are non-associative generalizations of MV-algebras. They are an algebraic counterpart of a non-associative propositional logic which generalizes the Lukasiewicz infinite valued logic and ...

The LPi and LPi/2 Propositional and Predicate Logics.

In fuzzy logic three main logics are investigated (Godel,product and Lukasiewicz logic). There are logics LPi and LPi1/2 uniting these three logics. We show an alternative axiomatic system of thes...

Fuzzy Logic and Piecewise-Linear Regression

McNaughton theorem of fuzzy logic states that the functions on the unit cube which admit representation by formulas of the Lukasiewicz propositional logic are exactly all continuous piecewise-linear functions (CPLF...

Equilibrium Semantics for IF Logic and Many-Valued Connectives

We connect two different forms of game based semantics: Hintikka’s game for Independence Friendly logic (IF logic) and Giles’s game for Lukasiewicz logic information emerges for a logic that extends both, ...

Computational Complexity of t-norm based Propositional Fuzzy Logics with Rational Truth Constants

If a continuous t-norm on [0,1] maps pairs of rationals into rationals then the corresponding fuzzy propositional calculus can be extended by rational truth constants and "bookkeeping" axioms for them. (Lukasiewicz t-norm is the cla...

Many-valued Horn Logic is Hard

In this work we show that for propositional Horn clauses a finite-valued conjunction operator (in particular under finite Lukasiewicz semantics) can induce additional nondeterminism. In order to prove this, we reduce the problem of ...
