摘要:

The well-known Romanoff theorem asserts that the set $\left\{p+2^k: p\right.$ is prime and $k \geq$ $0\}$ has a positive lower density, i.e., there exists an absolute constant $C_0$ such that $\left|\left\{n \leq X: n=p+2^k\right\}\right| \geq C_0 X$ for any sufficiently large $X$, which was proved by Romanoff in 1934. Nowadays the Romanoff theorem has been generalized in many different ways. For example, in 1950, Erdős 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.
