报告摘要：The well-known Romanoff theorem asserts that the set { p+2^��: p is prime and k≥ 0} has a positive lower density, i.e., there exists an absolute constant ��_0 such that |{n ≤ X : n = p+2^��}| ≥ ��_0X for any sufficiently large X. Nowadays the Romanoff theorem has been generalized in many different ways. In fact, as early as 1950, Erdos considered one kind of generalization of Romanoff theorem. In this talk, some previous and classical results concerning the Romanoff theorem will be retrospected. In addition, our recent progress on this topic will be introduced.
