I am trying to understand the definition of the double handlebody that is given here: https://warwick.ac.uk/fac/sci/maths/people/staff/karen_vogtmann/tcc2016/lecture_1_oct_15_2014_edited.pdf page 9 and 10. That is, it is $\#_{n} S^1 \times S^2$ or two handlebodies ($\#_{n} S^1\times D^2$) identif...

Since the list of new tags says (topology) x 2, I suppose that one question with that tag (perhaps the one where it was created) was deleted.
I have simply removed the tag from this instance: math.stackexchange.com/posts/2957001/revisions
This tag was mentioned, for instance, here: chat.stackexchange.com/transcript/3740/2017/10/12

Resolved (a first step, anyway). The topology⇒general-topology tag synonym has been removed. Problem: I feel that there are quite a number of questions tagged with both general-topology AND algebraic-topology where the former is not really fitting. My understanding being that General Topolo...

SEDE shows one deleted question with the (topology) tag: data.stackexchange.com/math/query/883845/… - of course, that is the status from the last update of the data in SEDE. The deleted question is: Show that $\int {a_n}\ \in l^1$ is the sum $\sum_{n=1}^\infty a_n$ using Lebesgue Theory.
