Every finitely generated ideal of a Leavitt path algebra is a principal ideal

Let E be an arbitrary graph and K be any field. For every non-graded ideal I of the Leavitt path algebra L_{ K}(E), we give an explicit description of the generators of I. Using this, we show that every finitely generated ideal of L_{ K}(E) must be principal. In particular, if E is a finite graph, then every ideal of L_{ K}(E) must be principal ideal.
