Spaces of Theories with Ideal Refinement Operators
Refinement operators for theories avoid the problems related to the myopia of many relational learning algorithms based on the operators that refine single clauses. However, the n...

Linear logical approximations
ract interpretation of programs relates the exact semantics of a programming language to an approximate semantics that can be effectively computed. We show that, by specifying ope...

Expressivity and completeness for public update logics via reduction axioms
In this paper, we present several extensions of epistemic logic with update operators modelling public information change. Next to the well-known public announcement operators, we ...

Weakly Algebraizable Logics
The class of weakly algebrizable logics is defined as the class of logics having monotonic and injective Leibniz operator. We show that "monotonicity" cannot be discarde...

Triangle algebras: A formal logic approach to interval-valued residuated lattices
In this paper, we introduce triangle algebras: a variety of residuated lattices equipped with approximation operators, and with a third angular point u, different from 0
