In this paper, we study the structure of $m$-quasi Einstein manifolds when there exists another distinct solution to the $(\lambda, n+m)$-Einstein equation. In particular, we derive sufficient conditions for the non-existence of such solutions.
Keywords: Bakry-Emery Ricci tensor, quasi-Einstein manifolds, the $(\lambda, n+m)$-Einstein equation
