On The Line Graph of Graph with Respect to Idempotents of a Ring
Let [Formula: see text] be a ring with nonzero identity and [Formula: see text] denotes the set of idempotents in [Formula: see text]. A graph of [Formula: see text] with respect to idempotents [Formula: see text] is a graph whose vertices are elements of [Formula: see text] and two vertices [Formula: see text] and [Fo...
