Right! to be more specific are we letting epsilon to be a/2? also for the nowhere dense part. there are many theorems to use in my book about proving something is nowhere dense. for instance we have " a subset is nowhere dense if int(cl(H)) = empty set or iff T- Cl(H) is dense. which shall i use or do u suggest to use another theorem?
