“…This remark -which is exemplified through the following example-suggests, in turn, that PI-based relevance acts differently in relation to relevance presented herein. b, ¬c, d, e}, {¬a, ¬b, ¬c, d, e}, {a, b, ¬c, ¬d, e}, {¬a, ¬b, ¬c, ¬d, e} , whereas, b, ¬c, d, e}, {¬a, ¬b, ¬c, d, e}, {a, b, ¬c, ¬d, e} -refer to Example 3 in (Perrussel et al, 2012) for details on how the set of worlds [K P I F ϕ] is produced. Therefore, [K F ϕ] = [K P I F ϕ], thus, K F ϕ = K P I F ϕ.…”
