A survey on just-non-\(\mathfrak X\) groups.
If \(\mathfrak X\) is a class of groups then a group that does not belong to \(\mathfrak X\) but all of whose proper quotient groups belong to \(\mathfrak X\) is called a just-non-\(\mathfrak X\) group. This paper gives a survey of some results about just-non-\(\mathfrak X\) groups that are connected to topological groups.
