Algebraic Aspects of Propositional Logic, and Future Work in Defeasible Reasoning

Talk by Nicholas Leisegang
This talk will consist of two parts. In the first part, I will discuss work from my masters thesis on algebraic aspects of propositional logic. In particular, I will provide a brief introduction into universal algebra, and describe how a propositional theory of logic corresponds to a variety of universal algebra in a generalized setting. Using this correspondence and certain examples, we will then characterise a notion of completeness in an algebraic setting for propositional logics. In the second part of the talk, I will talk a little bit about the area of interest and the central questions for my PhD studies. Specifically, I will give a brief introduction to KLM style defeasibility and introduce the problems I am working on with regards to introducing KLM-style reasoning into more expressive logics.
