The Köthe conjecture states that if a ring R has no nonzero nil
ideals then R has no nonzero nil one-sided ideals. Although for more than
70 years significant progress has been made, it is still open in general. In
this paper we survey some results related to the Köthe conjecture as well as
some equivalent problems.
