Abstract
Objective: To generalize the -skew McCoy rings. Methods: For a ring endomorphism , we call a ring Central -skew McCoy if for each pair of nonzero polynomials and satisfy , then there exists a nonzero element with . Findings: For a ring R, we show that if for each idempotent , then is Central -skew McCoy if and only if is Central -skew McCoy if and only if is Central -skew McCoy. Also, we prove that if for some positive integer , is Central -skew McCoy if and only if the polynomial ring is Central -skew McCoy if and only if the Laurent polynomial ring is Central -skew McCoy. Moreover, we give some examples to show that if is Central -skew McCoy, then is not necessary Central -skew McCoy, but and are Central -skew McCoy, where and are the subrings of the triangular matrices with constant main diagonal and constant main diagonals, respectively.
