I am quite glad you are back, and alive!

Well, that is form of death nowadays. I wish you an happy resurrection.

You are right. Take your time and ask any question. I will try to sum
up through the next posts.

No, we have all the time. I just answered to posts, and made
elementary recalls of math. But I realize that some people have not
follow any course in set theory. In Belgium it was taught as "modern
math" during 10 years in high school, and then it has disappeared
(alas 1000X). The discrepancy between the math level of different
people is very big, but the shortcut I am pursuing now, should not be
insurmountable. I will make the next posts as self-contained as
possible, but please interrupt when you feel I am esoteric.
Have a good day,
Bruno
