| Popis: | We explore almost-normality in Isbell-Mr\'owka spaces and some related concepts. We use forcing to provide an example of an almost-normal not normal almost disjoint family, explore the concept of semi-normality in Isbell-Mr\'owka spaces, define the concept of strongly $(\aleph_0 Comment: Postprint, accepted in Topology and its Applications |
