Query: On Leibniz algebras, whose subalgebras are either ideals or
  self-idealizing   A subalgebra S of a Leibniz algebra L is called self-idealizing in L if it
coincides with its idealizer IL(S). In this paper we study the structure of
Leibniz algebras, whose subalgebras are either ideals or self-idealizing.
