We will show that under suitable conditions on and , there exists a positive number such that the nonhomogeneous elliptic equation in , , , has at least two positive solutions if , a unique positive solution if , and no positive solution if , where is the entire space or an exterior domain or an unbounded cylinder domain or the complement in a strip domain of a bounded domain. We also obtain some properties of the set of solutions.
