Abstract
We formalise justification in the topological argumentation model and define knowledge and belief based on justification. In addition to revealing that the notions of knowledge and belief based on justification satisfy Stalnaker’s BK system except for the closure principle, the main contribution of this paper is a counter-intuitive result about the notion of knowledge based on justification, which is related to the no false lemmas.

When no confusion arises, \(\tau _{\mathcal {E}_0}\) will be denoted simply by \(\tau \).

A topology over a non-empty domain X is a family \(\tau \subseteq 2^X\) containing both X and \(\varnothing \), and closed under both finite intersections and arbitrary unions. The elements of a topology are called open sets. The topology generated by a given \(\mathcal {Y}\subseteq 2^X\) is the smallest topology \(\tau _{\mathcal {Y}}\) over X such that \(\mathcal {Y}\subseteq \tau _{\mathcal {Y}}\).

Attack edges involving the empty set are not drawn.
