Özet
We give necessary and sufficient conditions on a directed graph E for which the associated Leavit path algebra L-K(E) has at least one full idempotent. Also, we define E-n, n >= 0 sub-graphs of E and show that L-K(E) has at least one full idempotent if and only if there is a sub-graph Er such that the associated Leavitt path algebra L-K(E-r) has at least one full idempotent.
