The main objective of this work is to study (quasi-)morphic prop- erty for skew polynomial rings. Let R be a ring and be a ring homomor- phism on R. We show that if R[x; ]=(xn+1) (n 1) is quasi-morphic then so is R. It is also proved that R is a regular ring provided that R[x; ]=(xn+1) is morphic. Some applications of our results are provided.
