Eduardo Barrio, Federico Pailos & Damian Szmuc forthcoming in the Logic Journal of the IGPL!

The paper entitled "A Paraconsistent Route by Semantic Closure", written by Eduardo Barrio, Federico Pailos and Damian Szmuc discusses the application of the so-called Goodship Project in order to obtain non-trivial functionally complete transparent theories of truth built on top of paraconsistent logics.

Some pictures of our Reading Group sessions

Federico Matías Pailos discussing the paper "Theories of truth and the maxim of minimal mutilation" by Ole Thomassen Hjortland, and Paula Teijeiro presenting "Many-valued logic of informal provability" by Rafal Urbaniak and Pawel Pawlowski in our Reading Group.


Damian Szmuc forthcoming in the Journal of Applied Non-Classical Logics!

The paper "Defining LFIs and LFUs in extensions of infectious logics", written by Damian Szmuc has been accepted for publication in the Journal of Applied Non-Classical Logics!

The paper discusses subsystems of the logics of nonsense, due to Bochvar and Hallden, and proposes to extend them with a classical negation, thereby defining an extensive collection of new Logics of Formal Inconsistency and Logics of Formal Undeterminedness.

Eduardo Barrio, Lucas Rosenblatt and Diego Tajer forthcoming in Synthese!

The paper "Capturing naive validity in the Cut-Free approach", written by Eduardo Barrio, Lucas Rosenblatt, and Diego Tajer, has been accepted for publication in Synthese!

The paper shows that the usual theories of validity cannot capture most meta-inferences, and discusses some possible ways of avoiding this problem by strengthening the Validity rules.

[CALL FOR PAPERS] Special Issue of Logic Journal of the IGPL

# CALL FOR PAPERS: Logic Journal of the IGPL #

Special issue:
Recovery Operators and Logics of Formal Consistency & Inconsistencies

• SPECIAL ISSUE EDITORS
Walter Carnielli (CLE-UNICAMP) (walter.carnielli@gmail.com)
Eduardo Barrio (CONICET-UBA) (eabarrio@gmail.com)

• CALL FOR PAPERS
Submissions must be in clearly-written English. Instructions to Authors are on http://ift.tt/2bcq70d

To submit a contribution send a one page abstract to: eabarrio@gmail.com (c/copy to walter.carnielli@gmail.com)

Contributing papers are invited from both Philosophers, Logicians, Mathematicians and Computer Scientists.

• FOCUS OF THE PAPERS
We invite papers that share a strong conceptual interest in the logics of formal inconsistency and formal inconsistency (LFIs) as tools to recovery some concept that traditionally cannot be expressed by plain logic (the paradigmatic case being paraconsistent logics). We are specially interested in papers that develops different applications of consistency and inconsistency operators to capture notions such as just truth, accidentally true, classicality, strong negation, indeterminateness, etc.

• SCOPE OF THE SPECIAL ISSUE
All papers related to Logics of Formal Inconsistencies those falling into the categories below are welcome:
- Consistency, Classicality and Recovery Operators
- Avoiding Hierarchies of Languages with Paraconsistent Logics
- Capturing Classical Logic using LFIs
- Recovery Operators in non-classical logics Many-valued
- Paraconsistent Logics with strong negation
- Modalities and Consistency Operators.
