Jan 6, 2017 at 19:06 comment added Igor Belegradek Oh, I see that I misunderstood your question. I was explaining the existence of a closed tubular neighborhood. After looking at the definition of a closed tubular neighborhood in Kosinski's book (p.46) I agree that it looks sloppy. He never defines a disk bundle (as far as I can see), but I suspect he means a linear disk bundle.
