Abstract
In this paper, the endomorphism monoid of Pn¯, the complement of a path PnPn with nn vertices, is explored explicitly. It is shown that End(Pn¯) is orthodox. Some enumerative problems concerning End(Pn¯) are solved. In particular, the endomorphism spectrum and the endomorphism type of Pn¯ are given.
